        From Daniel Carroll.

2001-04-27  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (_AC_OUTPUT_CONFIG_STATUS): Use two backslashes

2001-04-24  Akim Demaille  <akim@epita.fr>

        On HP-UX 10 `ranlib --version' creates `./--version'.

        program with --version.

2001-04-22  Jim Meyering  <meyering@lucent.com>

        * acfunctions.m4 (AC_FUNC_MEMCMP): Remove `int main () {' and the
        trailing `}', since AC_LANG_PROGRAM provides them.

2001-04-20  Akim Demaille  <akim@epita.fr>

        * configure.in: Bump to 2.49f.

2001-04-20  Akim Demaille  <akim@epita.fr>

2001-04-20  Nicolas Joly  <njoly@pasteur.fr>

        * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Be robust to missing

        inline setting up of AS_MESSAGE_FD.
        (AS_MESSAGE_LOG_FD): Do not define, so that AS_MESSAGE does not
        output in it before...
        (_AC_INIT_CONFIG_LOG): here, which is run after the handling of
        options.

2001-04-18  Steven G. Johnson  <stevenj@alum.mit.edu>

        * doc/autoconf.texi: Replace documentation for obsolete

2001-04-17  Steven G. Johnson  <stevenj@alum.mit.edu>

        * doc/autoconf.texi: Fixes for punctuation and grammar..  Replace

        * acgeneral.m4 (_AC_INIT_VERSION): Use AC_PACKAGE_NAME and
        AC_PACKAGE_VERSION only if they are defined.

        Standards.

2001-04-13  Steven G. Johnson  <stevenj@alum.mit.edu>

        * doc/autoconf.texi: Still more minor modifications for clarity,
        felicity, and grammar.

2001-04-11  Steven G. Johnson  <stevenj@alum.mit.edu>

        * doc/autoconf.texi (AC_F77_WRAPPERS): Mention C++ as well as C.
        In the example, don't #ifdef F77_FUNC before using it, as that
        would push any errors to link-time rather than compile-time; note
        that the user can test this to invoke alternative behavior.

2001-04-11  Akim Demaille  <akim@epita.fr>

        * autoconf.sh (Task script): Be sure that `forbidden.rx' and
        `allowed.rx' exist when AWK loads then.
        Reported by Rainer Orth.

2001-04-11  Steven G. Johnson  <stevenj@alum.mit.edu>

        * doc/autoconf.texi: A few more minor modifications for clarity,
        grammar, and formatting.

2001-04-10  Lars J. Aas  <larsa@sim.no>

        * Makefile.am: AC_SUBST fixes for PACKAGE_NAME, VERSION, PACKAGE...
        * configure.in: Moved here.
        Suggested by Akim Demaille and Raja R Harinath.

2001-04-10  Lars J. Aas  <larsa@sim.no>

        * acgeneral.m4 (_AC_OUTPUT_CONFIG_STATUS):  Re-enable logging to
        `config.log' from `config.status', but delay logging till after
        command line option processing.

2001-04-10  Lars J. Aas  <larsa@sim.no>

        * autoupdate.in (print_usage): print "\ at end of line does not
        work as expected, so change block to here-doc instead.
        (print_version): Same.

2001-04-09  Steven G. Johnson  <stevenj@alum.mit.edu>

        * doc/autoconf.texi: Replace all tab characters with (8) spaces,
        lest the formatting of example code, etcetera, be messed up.

2001-04-09  Steven G. Johnson  <stevenj@alum.mit.edu>

        * doc/autoconf.texi: Rephrase various parts for clarity, felicity,
        and/or grammar.

2001-04-09  Steven G. Johnson  <stevenj@alum.mit.edu>

        * doc/autoconf.texi: Clean up cache documentation: Document
        --config-cache/-C option, and recommend instead of --cache-file.
        Indent example AC_CACHE_VAL macros for clarity.  Add new
        "Cache Checkpointing" section for AC_CACHE_SAVE (and
        AC_CACHE_LOAD), so that the "Cache Files" section focuses solely
        on features visible to end-users (e.g. to better fit the cross
        references).  Various minor rewordings for clarity, felicity,
        and/or grammar.

2001-04-09  Steven G. Johnson  <stevenj@alum.mit.edu>

        * doc/autoconf.texi: Revert to "configure.in" in the history, since
        "configure.ac" wasn't used in the past, and in any case it is
        probably a good idea to preserve this section verbatim.

2001-04-09  Steven G. Johnson  <stevenj@alum.mit.edu>

        * AUTHORS: Fix grammar.

2001-04-09  Lars J. Aas  <larsa@sim.no>

2001-04-04  Lars J. Aas  <larsa@sim.no>

        * acgeneral.m4 (_AC_INIT_DEFAULTS): Produce better version
        information for config.log header.
        (_AC_INIT_VERSION): Produce better version information for
        `configure --version'.

2001-03-30  Steven G. Johnson  <stevenj@alum.mit.edu>

        * doc/autoconf.texi: Use "invalid" instead of "illegal," as
        suggested by the GNU coding standards.

        (AT_INIT): Use $PATH_SEPARATOR for walking the path.
        * autoconf.sh: Be DOS-friendly when setting as_me and M4.

2001-03-27  Tim Van Holder  <tim.van.holder@pandora.be>

        `touch'.

2001-03-19  Akim Demaille  <akim@epita.fr>

        * autoscan.pl, autoupdate.in: Use `use' instead of `require' to

2001-03-13  Tim Van Holder  <tim.van.holder@pandora.be>

        * tests/aclocal.m4: Fix some typos.  Also ignore $PATH_SEPARATOR.

        * tests/tools.at (AWK portability): Use AT_CHECK to check for GNU
        AWK so that there is always a AT_CHECK between
        AT_SETUP/AT_CLEANUP.
        Reported by Nicolas Joly.

2001-03-13  Akim Demaille  <akim@epita.fr>

        * tests/tools.at: Be sure to remove configure.ac~.

2001-03-13  Raja R Harinath  <harinath@cs.umn.edu>

        * autoupdate.in (File::Basename): Use package.
        (%ac_macros, %au_macros): Save only base filenames.

2001-03-08  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_OUTPUT): In the AU_DEFUN definition, don't try
        to issue an obsolete message, it can't work for macros being
        defined both with AC_DEFUN and AU_DEFUN.
        Hence do it in the AC_DEFUN definition.

2001-03-06  Pavel Roskin  <proski@gnu.org>

        * tests/base.at (AC_TRY_*): Escape `^' - it's a pipe command

        Reported by Nicolas Joly.

2001-03-05  Akim Demaille  <akim@epita.fr>

        * tests/atgeneral.m4 (AT_INIT): Register at-setup-line and

        really a test.
        Reported by Pavel.

2001-03-04  Pavel Roskin  <proski@gnu.org>

        * tests/atgeneral.m4 (AT_INIT): s/am_me/as_me/. Quote AT_CHECK

        * tests/atgeneral.m4 (AT_INIT): Warn when at-check-line is
        missing.
        * tests/tools.at (Syntax of the scripts): Use AT_CHECK to test

        Reported by Harlan Stenn.

2001-02-28  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (_AC_INIT_PREPARE_FS_SEPARATORS): Use `.;.' instead
        of `.;`pwd`': if pwd is c:/foo, we might walk through `.:c'
        (fails), and then `/foo' which might succeed, resulting in
        believing `;' is the right path separator.

2001-02-26  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AH_VERBATIM, AH_TEMPLATE): New, use AS_ESCAPE, not

2001-02-25  Tim Van Holder  <tim.van.holder@pandora.be>

        * autoupdate.in: Support DOS paths.  Initialize $tmp to
        avoid warnings.  Default $autoconf to 'autoconf'.

2001-02-25  Akim Demaille  <akim@epita.fr>

        * autoupdate.in (&END): Try to preserve the exit status.
        Use backquotes where more readable.
        Internal details should be dumped when $debug, not when $verbose.

2001-02-25  Akim Demaille  <akim@epita.fr>

        * autoupdate.in (&mktmpdir): New.
        (&END): Remove $tmp.
        (&parse_args): Handle -d and -l.

2001-02-25  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (_AC_INIT_PREPARE): Remove conf$$* on exit.
        * m4sh.m4 (_AS_LN_S_PREPARE, _AS_BROKEN_TEST_PREPARE):
        s/conftest/conf$$/ to avoid race conditions.
        From Lars J. Aas.

2001-02-25  Akim Demaille  <akim@epita.fr>

        * acspecific.m4 (AC_PROG_INSTALL): Use ac_path_separator.
        Restore the IFS earlier.
        Suggested by Tim Van Holder.

2001-02-25  Akim Demaille  <akim@epita.fr>

        * m4sh.m4 (_AS_TEST_PREPARE): Rename as...

        The recent addition of `exit's prototype in confdefs.h causes

        Reported by Wolfgang Mueller.

        * tests/torture.at (#define header templates): Include trash in
        confdefs.h.

        Reported by Nicolas Joly.
        * acgeneral.m4 (AC_OUTPUT_MAKE_DEFS) <confdef2opt.sed>: In the
        `quote' section, `p'rint the result.

        * m4sh.m4 (_AS_TEST_PREPARE): Discard output when testing `test
        -x' and `test -f' to avoid confusing users with error messages.

        with some shells adding backslash between fields and parsing the
        result for escapes.

2001-01-29  Jim Meyering  <meyering@lucent.com>

        * autoscan.pl: Do scan `configure.ac' when you claim it.

2001-01-29  Akim Demaille  <akim@epita.fr>

        * autoscan.pl: `Formatting++' changes: prototypes all the
        functions, no longer use `&' to call functions as it disables
        prototype checking, topological sort so that functions are defined
        before being used, and put an Autoconf like nice comment to
        describe the functions.
        (output): Accept a CONFIGURE_SCAN parameter, and open CONF.

2001-01-29  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_SITE_LOAD): Let config.log know what you load.

2001-01-27  Akim Demaille  <akim@epita.fr>

        (_AS_LN_S_PREPARE): Eve out from...
        * acspecific.m4 (AC_PROG_LN_S): here.  Adjust.
        * m4sh.m4 (AS_LN_S): New.
        (AS_SHELL_PREPARE): Call _AS_LN_S_PREPARE.

2001-01-26  Assar Westerlund  <assar@sics.se>

        (aclocal): Same as below for autoheader.

2001-01-26  Akim Demaille  <akim@epita.fr>

        * autoreconf.sh (autoheader): Run it when there is no template, as
        there is no risk to override a handwritten template.
        From Assar Westerlund.

        * aclang.m4: dnl AC_ARG_VAR's newline.

2001-01-26  Akim Demaille  <akim@epita.fr>

        * tests/mktests.sh: Handle DOS issues: directory separator, single
        dot in file names, and one actual bug: when set -e, running
        (false; true) will of course fail, use (false || true).
        From Tim Van Holder.

2001-01-26  Tim Van Holder  <tim.van.holder@pandora.be>

        * tests/Makefile.am (testsuite): Use testsuite.tmp, not
        testsuite-tmp as temporary file.

2001-01-24  Akim Demaille  <akim@epita.fr>

        * configure.in: Bump to 2.49d.

2001-01-24  Akim Demaille  <akim@epita.fr>

        * autoscan.pl (output): Detect/report a close failure.

2001-01-24  Akim Demaille  <akim@epita.fr>

        Preserve INSTALL too.

        * acgeneral.m4 (_AC_OUTPUT_FILES): Use ac_INSTALL for internal
        computations, and therefore use INSTALL where ac_given_INSTALL
        was used.
        (_AC_OUTPUT_SUBDIRS): There is no point in computing INSTALL in
        here.  It's not even used.

2001-01-24  Akim Demaille  <akim@epita.fr>

        While preserved in configure, srcdir is trashed in config.status.
        Reported by Ralf Corsepius.

        * tests/aclocal.m4 (AC_STATE_SAVE): It is ok to modify
        CONFIG_STATUS, DEFS, prefix and exec_prefix.
        It is OK to produce config.* files.

        AC_OUTPUT to check that it doesn't break anything by itself.
        * tests/torture.m4 (srcdir): New test, from Ralf Corsepius.
        * acgeneral.m4 (_AC_OUTPUT_FILES): Use ac_top_srcdir and ac_srcdir
        to preserve srcdir and top_srcdir.
        Remove any use of `ac_given_srcdir' as `$srcdir' being preserved
        is usable.

2001-01-24  Alexandre Duret-Lutz  <duret_g@epita.fr>

        configure -q did not work since 2000-11-03.

        * acgeneral.m4 (_AC_INIT_DEFAULTS_FDS): Don't check for $silent,

        instead of test -f.

        * autoscan.pl (@kinds, %generic_macro): New.
        (&init_tables): Use them.
        * acheaders: Run `autoconf -t AC_CHECK_HEADERS:'$1'' on the fileutils,

        * tests/Makefile.am (MACRO_FILES): Use '..', not '$(top_srcdir)'.

2001-01-24  Akim Demaille  <akim@epita.fr>

        Don't AC_SUBST too much, as it makes Automake include those
        variables in Makefiles, and drives autoscan to require unneeded
        programs.

        * acgeneral.m4 (_AC_INIT_PREPARE): Don't AC_SUBST CFLAGS,
        CPPFLAGS, CXXFLAGS and LDFLAGS.

        Don't use parens with `defined'.

2001-01-23  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (_AC_INIT_PREPARE): Be sure to quote hashes to
        avoid M4 thinking it's comments.

2001-01-23  Tim Van Holder  <tim.van.holder@pandora.be>

        * aclang.m4 (_AC_COMPILER_EXEEXT_O): Use
        AS_IF([AC_TRY_EVAL(ac_link)]) instead of AC_LINK_IFELSE to
        avoid depending on ac_exeext before it's found.
        (AC_PROG_CC, AC_PROG_CXX, AC_PROG_F77): Check for the
        executable extension BEFORE checking whether the compiler
        works, as that test depends on a correct ac_exeext.

2001-01-23  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (_AC_INIT_PREPARE) <trap>: Typo.

2001-01-22  Pavel Roskin  <proski@gnu.org>

        * autoscan.pl: Use "use strict". Declare all global variables
        or make them private. Make all local variables private.
        (find_autoconf): New, moved some code from the top level.
        Use %ENV outside quotes to eliminate a warning.

2001-01-22  Tim Van Holder  <tim.van.holder@pandora.be>

        * acspecific.m4 (AC_PROG_LN_S): Detect DJGPP < 2.04, which only
        supports 'ln -s' for executables.

2001-01-22  Akim Demaille  <akim@epita.fr>

        * autoscan.pl: Formatting changes.

2001-01-22  Akim Demaille  <akim@epita.fr>

        * autoscan.pl (&wanted): Don't register `Makefile' when
        `Makefile.in' is present.
        Factor the simplification of $name.
        (&scan_makefile, &scan_sh_file): Instead of counting the number of
        occurrences where a program/makevar is wanted, register file:line.

        Simply run `testsuite' with the failed tests instead of running
        the debug scripts, this avoids having zillions of banners `Testing
        Blabla 2.13' (another means to avoid these banners is to have the

        computed by _AC_PROG_CXX_EXIT_DECLARATION.

2000-11-23  Akim Demaille  <akim@epita.fr>

        Factor part of the prologue of the tests.

        * tests/atgeneral.m4 (AT_SETUP, AT_CLEANUP): No longer handle

2000-11-23  Akim Demaille  <akim@epita.fr>

        * tests/atgeneral.m4 (AT_SETUP): Don't build at-check-line, that's
        AT_CHECK's job.

2000-11-23  Akim Demaille  <akim@epita.fr>

        The debug scripts are only wrapper around testsuite, asking for a
        specific test.

        * tests/atgeneral.m4 (AC_INIT) <at_debug>: New variable, new
        option, -d, to disable the creation of the debug scripts (when
        testsuite was already launched from one).
        <at_test_count>: Really compute it instead of using the number of
        the last test run.

2000-11-23  Akim Demaille  <akim@epita.fr>

        Transform Autotest's body into a `for test; case $test'.
        As a known side effect, currently any code outside
        AT_SETUP/AT_CLEANUP is discarded.

        * acgeneral.m4 (_m4_divert(KILL)): Move to...
        * m4sugar.m4: here.
        * tests/atgeneral.m4 (AT_INIT): Use m4_divert_push/pop instead of

        Adjust the differences on the names of the builtins (define etc.).
        (AT_CASE): Remove, use m4_case.
        (AT_SETUP): Don't use `AT_group_description', `$1' is OK.
        * tests/atspecific.m4 (m4_for, m4_foreach): Remove, use those of
        M4sugar.
        * tests/m4sugar.at: Strengthen the quotation and adjust to the new
        macro names.

        * acgeneral.m4 (_AC_RUN_IFELSE): Instead of canceling the output
        of the test program, save it into the log.
        Save the exit status, and report it in the log when non zero.
        Just use `(./conftest)' instead of `(./conftest; exit)'.

2000-11-17  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (_AC_INIT_DEFAULTS) <ac_includes_default>: Include

        From Paul Eggert.

2000-11-16  Akim Demaille  <akim@epita.fr>

        Reorder the test suite so that low level features are tested
        before high level ones.

        * tests/semantics.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
        (missing templates): Move to...
        * tests/torture.at: here.
        Reorder the file so that the torture test is last.

        longer exist.

2000-11-16  Akim Demaille  <akim@epita.fr>

        POSIX doesn't require s/[^/]// to work.

        * m4/largefile.m4 (_AC_SYS_LARGEFILE_SOURCE): Remove, replaced by...
        (_AC_SYS_LARGEFILE_TEST_INCLUDES): this.
        (AC_SYS_LARGEFILE_MACRO_VALUE): Use AC_LANG_PROGRAM instead of
        _AC_SYS_LARGEFILE_SOURCE, i.e., don't pass
        _AC_SYS_LARGEFILE_TEST_INCLUDES by default: this isn't desirable
        when checking for fseeko.
        (AC_SYS_LARGEFILE): Pass AC_SYS_LARGEFILE_TEST_INCLUDES to
        _AC_SYS_LARGEFILE_MACRO_VALUE, since it no longer does this for us.

2000-11-16  Akim Demaille  <akim@epita.fr>

        Provide a means for escaping the forbidden patterns test.

        * tests/tools.at (Forbidden tokens): Test m4_token_allow.

        these exceptions.

2000-11-14  Paul Eggert  <eggert@twinsun.com>

        * acspecific.m4 (AC_SYS_LARGEFILE): Don't worry about
        whether fseeko and ftello are properly declared.
        * acfunctions.m4 (AC_FUNC_FSEEKO): New macro, which worries about
        fseeko (and presumably ftello).  Do not set _XOPEN_SOURCE; that
        causes too many problems in practice.
        * acfunctions (fteelo, fseeko): Trigger AC_FUNC_FSEEKO.
        * doc/autoconf.texi: Adjust.

2000-11-14  Akim Demaille  <akim@epita.fr>

        * BUGS: New file.
        Be sure to read this file if you're using a non released Autoconf.
        * tests/tools.at (Syntax of the scripts): The non built tools are
        in `$top_srcdir', not `..'.
        (autoconf --trace): When using `-i' we need the src tree, not the
        build tree.

2000-11-14  Akim Demaille  <akim@epita.fr>

        A single m4_require is enough.

        * m4sugar.m4 (_m4_require): $2 defaults to $1.
        Rename as...
        (m4_require): this.
        * acgeneral.m4 (_AC_REQUIRE): Remove, use m4_require if you want
        to get into the gory details.

        autoconf's warnings.

2000-11-14  Akim Demaille  <akim@epita.fr>

        Set AC_LANG_PREPROC_REQUIRE which replaces AC_REQUIRE_CPP.
        The main difference is that the former requires AC_LANG_COMPILER.

        * aclang (AC_LANG_PREPROC, AC_LANG_PREPROC(C), AC_LANG_PREPROC(C++))
        (AC_LANG_PREPROC(Fortran 77), AC_LANG_PREPROC_REQUIRE): New
        macros.  Issue a warning when looking for the Fortran 77
        preprocessor instead of an error.
        (AC_LANG_COMPILER): Check that it is run before the corresponding
        AC_LANG_PREPROC.
        (AC_PROG_C
        (AC_LANG_COMPILER_REQUIRE): Don't call directly
        AC_LANG_COMPILER(_AC_LANG), rather invoke AC_LANG_COMPILER so that
        the generic code in AC_LANG_COMPILER is run.
        (AC_REQUIRE_CPP): Use AC_LANG_PREPROC_REQUIRE.
        (AC_PROG_CC, AC_PROG_CXX): Don't require being run before the
        corresponding AC_LANG_PREPROC: AC_LANG_COMPILER does it.


        Propagate AC_LANG_PREPROC_REQUIRE.

        * acgeneral.m4 (AC_TRY_CPP, AC_EGREP_CPP): Use it instead of
        AC_REQUIRE_CPP.
        * acspecific.m4 (_AC_DECL_YYTEXT, AC_PATH_X): Don't
        AC_REQUIRE_CPP, inner macro will do it.
        * aclang.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_STRINGIZE)
        (AC_C_PROTOTYPES): Likewise.
        (AC_C_STRINGIZE): Yeeks!  The body of AC_CACHE_CHECK was not
        quoted.  Use @%:@ do assist Emacs.


        For some reason (don't ask), this revamping revealed that
        AC_PROG_CC_STDC, because of the `break', does not clean its tmp
        files.

        * aclang.m4 (AC_PROG_CC_STDC): Extract the creation of conftest.c
        out of AC_COMPILE_IFELSE.
        Be sure to clean the tmp files.

        * acfunctions.m4 (AC_FUNC_ALLOCA): Don't require AC_PROG_CPP,
        since (i) you actually need a compiler, (ii) AC_TRY_LINK handles
        it.
        * acheaders.m4 (AC_HEADER_STDC): Don't require AC_PROG_CPP,
        AC_TRY_CPP does it.

2000-11-14  Akim Demaille  <akim@epita.fr>

        Create acheaders.m4.

        * acgeneral.m4 (AC_CHECK_HEADER, AC_CHECK_HEADERS)

        Adjust all dependencies.

2000-11-14  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4: Spread some AS_EXIT and AC_MSG_ERROR.
        (AC_OUTPUT): Don't play with trap, use ac_clean_files.

2000-11-14  Akim Demaille  <akim@epita.fr>

        Use AC_MSG_ERROR in `config.status', but adjust AC_MSG_* to use $0

        (_AC_INIT_DEFAULTS_FDS): Append to AC_FD_LOG instead of creating
        it.  No longer insert the configure banner.
        (_AC_INIT_DEFAULTS): Create config.log with the banner.
        Define `as_me'.

        (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS, _AC_PROG_F77_V_OUTPUT): Use
        `$as_me' instead of `configure'.
        (AC_OUTPUT): Get rid of the UCA, and of the empty line when
        dumping confdefs.h into config.log.
        (_AC_OUTPUT_CONFIG_STATUS): Use _AC_INIT_DEFAULTS_FDS.
        Print a banner.
        Use AC_MSG_ERROR and AC_MSG_NOTICE.
        * acgeneral.m4 (AC_CACHE_LOAD, _AC_OUTPUT_FILES, _AC_OUTPUT_LINKS)
        (_AC_OUTPUT_HEADERS):  Use AC_MSG_NOTICE.

        AC_PROG_CC
        AC_LANG_COMPILER_REQUIRE

        AC_PROG_CC is expanded twice, because AC_PROG_CC provides

        * m4sugar.m4 (m4_location): When using its value, don't use

        * tests/semantics.m4 (AC_HAVE_FUNCS): New test.
        * tests/tools.at (autoupdate): As a benign side effect, updating a

2000-11-03  Akim Demaille  <akim@epita.fr>

        * autoconf.m4: Instead of reactivating the macros before reading
        Autoconf's files, do it afterwards, so that Autoconf promotes the

        Autoconf's files.  Adjust them.
        But for the time being, keep `define' alive for Autoconf.

        ambiguities let's rename `libm4' (M4 code) as `m4sugar':

        name coined by Lars J. Aas.

        * tests/mktests.sh (update_exclude_list, syntax_exclude_list): Add
        `AC_PREREQ'.
        * tests/tools.m4: Globally, don't use `../' to invoke the tested
        tools, since the PATH is properly set, and in most cases it
        obfuscates the test code.
        (autoupdating AC_PREREQ): New tests.

2000-10-23  Akim Demaille  <akim@epita.fr>

        In order to check that all the CPP symbols which are AC_DEFINE'd
        are properly templated, autoheader traces
        AC_DEFINE/AC_DEFINE_UNQUOTED.  Only literals can be traced, and
        actually tracing non literals produces invalid autoheader input.
        Hence, provide a means to trace calls to
        AC_DEFINE/AC_DEFINE_UNQUOTED with literals.

        * acgeneral.m4 (AC_DEFINE_TRACE, AC_DEFINE_TRACE_LITERAL): New
        macros.
        (AC_DEFINE, AC_DEFINE_UNQUOTED): Use AC_DEFINE_TRACE.

        * aclang.m4 (_AC_PROG_CC_G): Use the _AC_COMPILE_IFELSE macro
        instead of reinventing the wheel. This also takes care of a bug
        where the "-g" option was accepted if the compiler silently exits
        with status unequal to 0.
        (_AC_PROG_CXX_G): Likewise.
        (AC_PROG_CC): As _AC_PROG_CC_G depends on $ac_objext and

        fall back to `cp'.

2000-10-17  Morten Eriksen  <mortene@sim.no>

        * acgeneral.m4 (AC_CHECK_TOOL): As AC_CHECK_PROG first tests the
        value of the VARIABLE argument when looking for executables, we
        need to set it to the correct value from AC_CHECK_TOOL when not
        just passing on the incoming VARIABLE directly.
        (AC_CHECK_TOOLS, AC_PATH_TOOL): Likewise.

2000-10-17  Assar Westerlund  <assar@sics.se>

        (m4_diagnose): this.  Use m4_location.
        Adjust dependencies.
        (m4_errprint): New macro, similar to `errprint' but for an
        additional trailing `\n'.
        * acgeneral.m4 (AC_DEFUN, AC_DEFUN_ONCE): Define `m4_location($1)'

        Fix autoupdate: updating `AC_OUTPUT_COMMANDS' was failing because
        it includes another AU defined macro.

        * autoupdate.sh (input.m4:_au_defun): New macro.
        (au.m4): Use it instead of inlining _au_enable/_au_disable
        invocations in the definition of all these macros.

        (input.m4:_au_enable, input.m4:_au_disable): Use them.
        * tests/mktests.sh (update_exclude_list): Add `AC_OUTPUT'.
        Running it twice in a configure.in is not valid.
        Add `AC_LINK_FILES' since it requires arguments.

        title.

2000-10-12  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (_AC_SH_QUOTE): Issue an `obsolete' warning for use
        of backquotes, instead of a `syntax' warning.

2000-10-02  Pavel Roskin  <proski@gnu.org>

2000-09-25  Pavel Roskin  <proski@gnu.org>

        * autoheader.sh: Don't check status of variable assignments -

        * autoupdate.sh: Likewise.
        * autoconf.sh: Likewise. Also eliminated command substitution

        * tests/atspecific.m4 (_AT_CHECK_AC_MACRO): Check stderr from

        exits if any input file is missing.

2000-09-20  Pavel Roskin  <proski@gnu.org>

2000-09-19  Pavel Roskin  <proski@gnu.org>

        * acgeneral.m4 (AU_ALIAS): Do not use `defn' since then autoupdate
        would replace an old macro call with the new macro body instead of
        the new macro call.
        * tests/tools.m4 (autoupdate): Test an AU_ALIAS'd macro update.

2000-09-18  Jim Meyering  <meyering@lucent.com>

        * acfunctions.m4 (AC_FUNC_GETLOADAVG): Restore the initial value
        of LIBS.  Otherwise, everyone ends up linking with -lelf for some

2000-09-14  Pavel Roskin  <proski@gnu.org>

        * acgeneral.m4 (_AC_TRY_CPP): Don't filter out conftest.$ac_ext
        from the output - it is only printed by Visual C that gives
        correct exit status.
        * aclang.m4 (AC_PROG_CPP): Don't try '${CC-cc} -nologo -E'
        by the same reason.

2000-09-12  Pavel Roskin  <proski@gnu.org>

        * aclocal.m4 (_AC_PROG_CPP_WORKS): Don't use AC_REQUIRE_CPP -

2000-09-12  Ruediger Kuhlmann  <autoconf-list@ruediger-kuhlmann.de>

        * acspecific.m4 (AC_PROG_INSTALL): Exclude c:install on AmigaOS.

2000-09-12  Akim Demaille  <akim@epita.fr>

        The test suite fails on some hosts because for instance
          AC_INIT
          AC_CHECK_FUNC(exit)
        will not look for a compiler, it will just use `cc'.
        Macros that need a compiler should require one.

        * acgeneral.m4 (_AC_REQUIRE): New macro, which is actually the
        previous version of AC_REQUIRE plus the possibility to distinguish
        the name of the symbol being AC_PROVIDE'd, and the text to expand.
        (AC_REQUIRE): Reimplement in terms of _AC_REQUIRE.
        * aclang.m4 (AC_LANG_COMPILER, AC_LANG_COMPILER_REQUIRE)
        (AC_LANG_COMPILER(C), AC_LANG_COMPILER(C++))

        New macros.
        * acgeneral.m4 (AC_COMPILE_IFELSE, AC_LINK_IFELSE, AC_RUN_IFELSE):
        Require a compiler.
        (AC_TRY_RUN): Formatting changes.
        * acfunctions.m4 (AC_FUNC_SETPGRP): Quote properly.  The previous
        changes revealed the weaknesses of this macro.

2000-09-12  Pavel Roskin  <proski@gnu.org>

        * acgeneral.m4 (_AC_TRY_CPP): New macro. It runs the preprocessor
        and checks whether it produces errors or warnings. Don't put grep
        output into a variable, use another grep instead.
        (AC_TRY_CPP): Use _AC_TRY_CPP. Copy conftest.err to config.log
        if the case of an error.
        * aclang.m4 (AC_LANG(C), AC_LANG(C++), AC_LANG(Fortran 77)):
        define AC_LANG_ABBREV to the short language name.
        (_AC_PROG_CPP_WORKS): New macro. It checks whether the current
        preprocessor can be used to check for existence of headers.
        Most code taken from ...
        (AC_PROG_CPP): ... here. Use _AC_PROG_CPP_WORKS. Use shell
        "for" to find working CPP. Use AC_LANG_PUSH(C) and AC_LANG_POP -
        it's a macro for C only.
        (AC_PROG_CXXCPP): Rewritten using _AC_PROG_CPP_WORKS.

2000-09-12  Akim Demaille  <akim@epita.fr>

        * autoupdate.sh (sed): Look for GNU sed.

        * acgeneral.m4 (AC_ARG_ENABLE, AC_ARG_WIDTH): Add trailing
        semicolon to final fi.

2000-09-11  Pavel Roskin  <proski@gnu.org>

        * acgeneral.m4 (_AC_WARNING_ERROR_IFELSE)
        (__AC_WARNING_ERROR_IFELSE): New macros for checking whether
        warnings should be considered errors.
        (_AC_DIAGNOSE): Use _AC_WARNING_ERROR_IFELSE.

2000-09-11  Pavel Roskin  <proski@gnu.org>

        * doc/autoconf.texi (Preset Output Variables): Correctly specify
        what languages are affected by CPPFLAGS, LDFLAGS and LIBS.
        Extended description of LDFLAGS and LIBS.
        (Compilers and Preprocessors, C Compiler Characteristics):
        Recommend Automake as the source of ansi2knr.
        (Autoconf Language, Quotation and Nested Macros): English fixes.
        (Quotation and Nested Macros): Unclear example replaced with
        an explanation of when m4 expands quotes. Added explanation why
        unquoted calls are dangerous.

2000-09-08  Pavel Roskin  <proski@gnu.org>

        * doc/autoconf.texi: Always use one space before the opening
        parenthesis in @defmac.

2000-09-06  Morten Eriksen  <mortene@sim.no>

        * acspecific.m4 (_AC_OBJEXT): No longer use AC_COMPILE_IFELSE,
        which uses $ac_objext hence depends upon _AC_OBJEXT.
        * aclang.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_F77): Call
        _AC_OBJEXT before _AC_EXEEXT since the latter needs $ac_objext.

2000-09-06  Bernard Dautrevaux  <dautrevaux@objectlive.com>

        * acspecific.m4 (_AC_EXEEXT): Set extension to void if linking
        creates both an unsuffixed file and suffixed ones.

2000-09-06  Peter Eisentraut  <peter_e@gmx.net>

        * autoconf.texi: English and typo fixes.

        * acfunctions.m4 (AM_FUNC_ERROR_AT_LINE, AM_FUNC_FNMATCH,
        AM_FUNC_MKTIME, AM_FUNC_OBSTACK, AM_FUNC_STRTOD): Deactivate
        their AU_ALIAS definition: Automake 1.4 does not quote the name of
        these macros, hence when Autoconf reads Automake's definition the
        name is expanded with unpredictable results.

2000-08-09  Akim Demaille  <akim@epita.fr>

        * autoreconf.sh (Installing Autoconf extensions files): Remove.

2000-08-09  Akim Demaille  <akim@epita.fr>

        Enhance it in order to look for and report unexpanded macro.
        Don't let it pretend there are bugs in Autoconf (c:, the test
        suite makes this scenario pretty unlikely as opposed to an actual
        user bug.

        (AC_F77_LIBRARY_LDFLAGS): Use _AC_PROG_F77_V instead of
        simply "-v"

        set/shift shell commands.

        instead of 48, to pass the test on RISC/OS 4.52.

2000-07-11  Akim Demaille  <akim@epita.fr>

        !*^&$@ sed portability problems...  The test on AC_CHECK_TYPES is
        failing on RISC/OS 4.52 because of the forget-to-reset-the-flag
        bug in its sed.

        * acgeneral.m4 (_AC_OUTPUT_HEADERS): Work around this bug.

2000-07-11  Akim Demaille  <akim@epita.fr>

        * acspecific.m4 (AC_INT_16_BITS, AC_LONG_64_BITS): s/ac_check/ac_cv/.

2000-07-10  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS): Look for
        the input files first in $builddir, then $srcdir.
        Suggested by Lars J. Aas, designed by Alexandre Oliva.

2000-07-10  Lars J. Aas  <larsa@sim.no>

        * acgeneral.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS):
        Accept special filename '-' for stdin and stdout.

2000-07-10  Akim Demaille  <akim@epita.fr>

        Alexandre's suggestions.

        * autoreconf.sh (update.sh): Use `ls -1dt' instead of `-lt'.
        Use test instead of sed.
        <automake>: If automake is used, always run it: it has its own
        mechanism not to update if unneeded.

2000-07-10  Akim Demaille  <akim@epita.fr>

        * acspecific.m4 (_AC_PROG_ECHO): Modernize.

2000-07-10  Akim Demaille  <akim@epita.fr>

        Stop being ridiculous :*(

        * acgeneral.m4 (_AC_SHELL_DIRNAME):  When using m4 the argument
        is named `$1' not `$dir'.
        When using m4 you ought to quote properly.
        When using m4, you should check that there are not too many shell
        quotes (inside the macro itself, and where it is called).
        When you do this, Autoconf, hm, works better.

2000-07-10  Steven G. Johnson  <stevenj@alum.mit.edu>

        Improve --help documentation of important environment variables.

        * acgeneral.m4 (_AC_INIT_HELP): Direct reader to descriptions
        of useful variables at the end of the --help.
        (AC_ARG_VAR): Emphasize use of environment variables to override
        and/or help the configure script.  Ensure that a given variable
        is only documented once in the --help.
        (AC_CHECK_LIB): Call AC_ARG_VAR to document and register the
        LDFLAGS variable, and...
        (AC_CHECK_HEADER): do the same for the CPPFLAGS variable.
        * aclang.m4 (AC_PROG_CC): Call AC_ARG_VAR to document and register
        the CC and CFLAGS variables, and do the same for...
        (AC_PROG_CXX): CXX and CXXFLAGS, and...
        (AC_PROG_F77): F77 and FFLAGS.

2000-07-10  Akim Demaille  <akim@epita.fr>

        AC_LIBOBJ when used by AC_REPLACE_FUNCS should not complain for
        variables as argument.

        * acgeneral.m4 (_AC_LIBOBJ): Same as the former AC_LIBOBJ, but
        takes an additional argument: action to perform when non-literal
        argument.
        (AC_LIBOBJ): Use it.
        (AC_REPLACE_FUNCS): Use _AC_LIBOBJ, not AC_LIBOBJ.

2000-07-10  Akim Demaille  <akim@epita.fr>

        LANGUAGE should be neutralized too.

        * acgeneral.m4 (_AC_INIT_PREPARE_ENVIRONMENT): Do it.

2000-07-10  Akim Demaille  <akim@epita.fr>

        Set autoconf's default warnings to `syntax'.

        In fact, honor the most recent specification in the concatenation
        of `syntax',$WARNINGS,<options> in that order.
        Implement support for `none' and `noCATEGORY' so that the options
        may override the previous choices.
        Suggested by Didier Verna.

        * acgeneral.m4 (_AC_WARNING_IFELSE): New macro.
        (AC_WARNING_IFELSE): Use this macro to implement the new specs.
        (AC_WARNING): The empty category must not be used, default to
        `syntax'.
        * doc/autoconf.texi (autoconf Invocation, Reporting Messages): Adjust.
        * autoconf.sh: Adjust.
        Use `optarg' to fetch the arguments of options.
        Fix a bug in the handling of `--trace='.

        * acgeneral.m4 (AC_CACHE_VAL): Typo: the macro was complaining iff
        it shouldn't have.

2000-07-10  Akim Demaille  <akim@epita.fr>

        * autoreconf.sh (--install, --symlink): New options.

        `aclocal.m4' and that of the location Autoconf extensions.
        (-M, --m4dir): New option.
        (aclocal_flags): Do not use $localdir, but $m4dir.
        (localdir_opt): Remove, since $autoconf, $autoheader already
        include `-l $localdir'.

2000-07-10  Akim Demaille  <akim@epita.fr>

        * autoconf.sh (task install): We no longer use AC_INCLUDE.

2000-07-10  Akim Demaille  <akim@epita.fr>

        * acoldnames.m4: Remove the obsolete comments.  The technology is
        now detailed in `autoupdate'.
        Quote the names being defined.
        Formatting changes.

2000-07-10  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_DEFUNCT): Remove.
        (AC_RSH, AC_UNISTD_H, AC_USG, AC_MEMORY_H, AC_DIR_HEADER,
        AC_INT_16_BITS, AC_LONG_64_BITS): They're alive!...
        * doc/autoconf.texi (Obsolete Macros): but not fresh.

2000-07-10  Akim Demaille  <akim@epita.fr>

        * autoreconf.sh (debug): New variable.
        (tmp): s/ac/ar/.

        * doc/autoconf.texi: Adjust.

2000-07-10  Akim Demaille  <akim@epita.fr>

        Fix the bugs recently introduced in autoreconf.

        * autoreconf.sh: Don't run automake when the package is not using
        it.
        When checking whether autoheader should be rerun, don't ask
        config.h to be newer than stamp-h and vice-versa.
        Remove an unbalanced `fi'.

2000-07-10  Akim Demaille  <akim@epita.fr>

        * autoreconf.sh (run_aclocal): Rename as `uses_aclocal' to avoid
        the convention clash with autoconf.sh where `run_foo' is the
        command to run `foo'.
        (uses_autoheader): New variable.

2000-07-10  Akim Demaille  <akim@epita.fr>

        * autoreconf.sh (update.sh): New sub program.
        Use it in the whole process.
        (acconfig_h): New variable.

2000-07-10  Akim Demaille  <akim@epita.fr>

        * autoreconf.sh <run_aclocal>: Use false/: instead of no/yes.
        Formatting and factoring changes.

2000-07-10  Akim Demaille  <akim@epita.fr>

        * autoreconf.sh: You too can have a $tmp dir if you wish.
        (alflags.sed): New sub sed program.
        Compute the flags of aclocal from Makefile.am instead of
        Makefile.in, it is unlikely that aclocal be used but not automake,
        while it is convenient to be able to run autoreconf even if
        automake was not run yet.
        Use `autoconf --trace' to get the list of configuration headers.

2000-07-10  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_PLAIN_SCRIPT): New macro.
        * tests/base.m4 (m4_wrap, AC_REQUIRE, AC_SHELL_MKDIR_P): Use it.
        * autoconf.sh: Properly handle the case where `$output' is `-'
        (i.e., stdout).
        Handle `-ofile', not just `-o file'.

2000-07-10  Akim Demaille  <akim@epita.fr>

        * autoreconf.sh: Formatting changes.
        When verbose, display exactly what you do, not just a synopsis.
        When using `$verbose' don't use quotes to avoid spurious spaces
        for empty arguments.

2000-07-10  Akim Demaille  <akim@epita.fr>

        * autoreconf.sh (force): Instead of yes/no, use :/false.
        Adjust the code.
        (automake_deps, automake_force): No longer used.

2000-07-10  Akim Demaille  <akim@epita.fr>

        words from Paul about `|' with expr(1).

2000-07-10  Akim Demaille  <akim@epita.fr>

        * aclang.m4: Promote s,,, over s%%%, and `sed prog' over `sed -e
        prog'.
        * acgeneral.m4: Likewise.
        * acspecific.m4: Likewise.
        * doc/autoconf.texi (Limitations of Usual Tools, Coding Style):

        * doc/autoconf.texi: Free Franc,ois Pinard from iftex and ifinfo,
        use @,c.
        Don't use `@code{m4}' when you mean M4, just as you shall not say
        `@code{cc}' when you refer to the C language.

2000-07-10  Akim Demaille  <akim@epita.fr>

        * aclang.m4 (AC_LANG(C), AC_LANG(C++), AC_LANG(Fortran 77)): Set

        * doc/autoconf.texi (Multiple Cases, Quotation Rule Of Thumb):
        Follow the coding style.

2000-07-10  Akim Demaille  <akim@epita.fr>

        * doc/autoconf.texi (Obsoleting Macros): Is not a subsection of
        `Dependencies Between Macros', but rather a section of `Writing
        Macros'.

2000-07-10  Akim Demaille  <akim@epita.fr>

        * doc/autoconf.texi (Coding Style): New node.

2000-07-07  Akim Demaille  <akim@epita.fr>

2000-07-07  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (_AC_SHELL_DIRNAME): Return `.', not `' when there

2000-07-07  Franc,ois Pinard  <pinard@iro.umontreal.ca>

        * tests/atgeneral.m4 (AT_CHECK): Fix a redirection problem.

2000-07-07  Akim Demaille  <akim@epita.fr>

        AC_REVISION must not AC_REQUIRE AC_INIT, it leaves the diversions
        in a messy state.  Don't even try to emulate AC_REQUIRE: just
        introduce a diversion just for AC_REVISION, and let the magic
        happen.
        Fixes Autoconf PR/134, from Raja R Harinath.

        * acgeneral.m4 (_AC_DIVERT(REVISION)): New diversion.

2000-07-07  Martin Wilck  <martin@tropos.de>

        * aclang.m4 (AC_F77_LIBRARY_LDFLAGS): Keep -lm, if a Fortran
        compiler needs it, it is likely to be required when linking C/C++
        with Fortran.
        <-YP,*>: Fix the list of arguments to loop on.
        Don't mess with the user variable name space.
        <ac_ld_run_path>: Prepend LD_RUN_PATH directories with -R only
        when running Solaris (without this, link errors occur).

        * acgeneral.m4 (_AC_INIT_PARSE_ARGS, AC_CHECK_TOOLS): Change
        warning message printed when only --host is given. Fix printing
        of multiple compiler cache values, use PATH argument.
        * aclang.m4 (AC_LANG_COMPILER_WORKS): Print the cross compile
        status, fix problem where two results were printed at once.

2000-07-06  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (_AC_SHELL_TMPDIR): Typo.

2000-07-06  Alexandre Oliva  <oliva@lsd.ic.unicamp.br>

        * acgeneral.m4 (_AC_SHELL_DIRNAME): Behave properly when the
        argument has trailing slashes, and when its depth is just one
        (`/tmp').

2000-07-06  Lars J. Aas  <larsa@sim.no>

        * acgeneral.m4 (_AC_SHELL_DIRNAME): New macro.
        (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS, _AC_OUTPUT_LINKS):

2000-07-06  Martin Wilck  <martin@tropos.de>

        * aclang.m4 (AC_PROG_F77): Add two compilers,
        lf95 (Lahey/Fujitsu Fortran) and pgf77 (Portland Group Fortran)
        (_AC_PROG_F77_G): Some Fortran compilers produce stdout/stderr
        output even if no errors occur - check exit status rather than
        output.

2000-07-05  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (_AC_SHELL_TMPDIR): When using `mktemp -d', be sure
        that the directory was created: under Ultrix 4.3 it just returns
        a name, but does not create the directory.
        Reported by Christian Krackowizer.

        * acgeneral.m4 (build_alias): Set to host_alias if --build is not
        given but --host is, and enable cross-compile auto-detection.  If
        both are, and are different, enable cross compilation.
        (AC_CANONICAL_HOST): Adjust help message.
        (cross_compiling): Enclose in quotes when testing.
        * aclang.m4 (_AC_LANG_COMPILER_WORKS): If cross_compiling is

        * doc/install.texi: Likewise.

2000-06-27  Jim Meyering  <meyering@lucent.com>

        From Volker Borchert.

2000-06-26  Akim Demaille  <akim@epita.fr>

        * doc/autoconf.texi: Fix various typos.

        (Language Choice): Don't mention cross_compiling here, do it...
        (Specifying Names) <--host>: here.
        (Obsoleting Macros): Don't document AC_DEFUNCT, it's going to be
        removed anyway, obsoleted itself by AU_DEFUN.

2000-06-26  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_CACHE_VAL): Swap the arguments of `regexp'.

        (Canonicalizing): here.
        Clarify the difference between the `foo_target' and `foo'
        variables.

2000-06-26  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_CONFIG_LINKS, AC_CONFIG_HEADERS,
        AC_CONFIG_COMMANDS, AC_CONFIG_FILES): Use a shell variable instead
        of an m4 variable to store what must be done, so that sh
        conditionals are honored.
        (_AC_OUTPUT_LINKS, _AC_OUTPUT_HEADERS,

        * acgeneral.m4 (AC_CACHE_VAL): Too many people put AC_DEFINE in
        the commands-to-set-it part of it.  Give them a warning.

2000-06-26  Akim Demaille  <akim@epita.fr>

        * doc/autoconf.texi (Prerequisite Macros): More about AC_REQUIRE.

2000-06-26  Akim Demaille  <akim@epita.fr>

        Given better names to the diversions.

        * acgeneral.m4 (_AC_DIVERT(NORMAL_2), _AC_DIVERT(NORMAL_3),
        _AC_DIVERT(NORMAL_4)): Delete, unused.

        Rename as _AC_DIVERT(PREPARE), _AC_DIVERT(BODY),
        _AC_DIVERT_DIVERSION.

2000-06-26  Akim Demaille  <akim@epita.fr>

        The current implementation of AC_REQUIRE fails on

        | AC_DEFUN([TEST1],  [REQUIRE([TEST2a])REQUIRE([TEST2b])])
        | AC_DEFUN([TEST2a], [])
        | AC_DEFUN([TEST2b], [REQUIRE([TEST3])])
        | AC_DEFUN([TEST3],  [REQUIRE([TEST2a])])
        |
        | AC_INIT
        | TEST1

        because it produces TEST3; TEST2a; TEST2b; TEST1.
        Fix this bug, implement the solution provided by Axel Thimm,
        and test AC_REQUIRE.

        * acgeneral.m4: Document this implementation.
        (_AC_DEFUN_PRO, _AC_DEFUN_EPI, AC_REQUIRE): Be sure that macros
        are emitted in the same order as they are expanded.
        (AC_REQUIRE): Forbid being calling out of an AC_DEFUN'd macro (in
        particular the top level).
        * tests/base.m4 (AC_REQUIRE): New test.

2000-06-26  Akim Demaille  <akim@epita.fr>

        A macro which is not defined with AC_DEFUN should not be
        AC_REQUIRE'd, since it doesn't AC_PROVIDE itself.

        * acgeneral.m4 (AC_REQUIRE): Issue a warning when after expansion,
        the macro is not AC_PROVIDE'd.

2000-06-26  Akim Demaille  <akim@epita.fr>

        Various cleanups.

        _AC_INIT_PREPARE, _AC_CANONICAL_SPLIT, _AC_CHECK_TYPE_NEW,

        they are not related to AC_REQUIRE in any way.
        * acspecific.m4 (AC_PROG_ECHO, _AC_DECL_YYTEXT, _AC_PATH_X_XMKMF,
        _AC_PATH_X_DIRECT): Define via `define' instead of `AC_DEFUN'.

        (AC_PATH_TOOL): Fix same bugs as in 6/9/00 fixes to AC_CHECK_TOOL.
        Pass correct arguments to AC_CHECK_PATH (different from
        AC_CHECK_PROG).  Use AC_CHECK_PATH cache variable, not
        AC_CHECK_PROG var, and use two variables for two invocations as
        above.  Quote AC_CHECK_* args.

2000-06-16  Akim Demaille  <akim@epita.fr>

        The test suite reveals AC_OUTPUT_MAKE_DEFS fails on RISC/OS.

        Move the documentation of AC_CACHE_SAVE and AC_CACHE_LOAD...
        (Cache Files): into here.

2000-06-09  Steven G. Johnson  <stevenj@alum.mit.edu>

        * acgeneral.m4 (AC_CHECK_TOOL): Even if VALUE-IF-NOT-FOUND is not
        specified, we should still check whether PROG-TO-CHECK-FOR
        actually works before returning it when the prefixed program is
        not found. Also, fixed a bug where it failed to pass the PATH
        argument in the second call to AC_CHECK_PROG.

2000-06-09  Akim Demaille  <akim@epita.fr>

        * aclang.m4 (AC_F77_LIBRARY_LDFLAGS): Fixed bug where
        compiler output to stdout was not caught and interpreted.

2000-06-09  Akim Demaille  <akim@epita.fr>

        `autoconf --trace' dies on filenames with `:'.
        Reported by Mark Elbrecht.

        * autoconf.sh <trace> (trace2m4.sed): Use `..*' instead of
        `[^:][^:]*' to catch file names.  The rest of regex is probably
        precise enough to avoid incorrect parsing.

2000-06-09  Akim Demaille  <akim@epita.fr>

        * acspecific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE): Always initialize

        * aclang.m4 (AC_F77_LIBRARY_LDFLAGS): Fix problem on Cray due to
        confusion from the link command getting echoed in quotes.  In the
        future, a more general fix for quoted arguments with spaces might
        be better.

2000-06-07  Akim Demaille  <akim@epita.fr>

        Hard (code) X.

        * acspecific.m4 (_AC_PATH_X_DIRECT): Hard code `X11/Intrinsic.h'
        instead of using `ac_x_direct_test_include', likewise for `Xt' and
        `ac_x_direct_test_lib', `XtMalloc' and
        `ac_x_direct_test_function'.

2000-06-07  Akim Demaille  <akim@epita.fr>

        * acspecific.m4 (AC_PATH_X): Use AC_DIVERT.

        Suggested by Mo DeJong.

2000-06-05  Steven G. Johnson  <stevenj@alum.mit.edu>

        * aclang.m4 (AC_C_CHAR_UNSIGNED): Use the new compiler-test
        technology so that we can do the test via compilations only.  Also
        use (char) -1 instead of (char) 255 to check if char is unsigned.

2000-05-28  Jim Meyering  <meyering@lucent.com>

        looking for the executable.
        * autoupdate.sh: Likewise.
        * autoheader.sh: Likewise.
        Suggested by Alexandre Oliva.

2000-05-26  Akim Demaille  <akim@epita.fr>

        Thanks to --program-transform-name, `autoconf' might be install as
        `yo-man-i-am-the-all-mighty-AVt0c0nF-eh-eh'.  But when
        `yo-man-i-am-the-all-mighty-AVt0h3Ad3R-eh-eh' and the other tools
        want to trace, they might stupidly invoke the program named
        `autoconf' instead.  Pfff, stupid scripts :)

        * Makefile.am (editsh): Transfer the names of the install
        `autoconf' and `autoheader'.
        * autoconf.sh: Add a missing period at the end of the comment
        # Parse command line
        Make sure to have a ChangeLog much longer than the patch.
        * autoheader.sh: Use the right `autoconf'.

2000-05-25  Steven G. Johnson  <stevenj@alum.mit.edu>

        Don't use f2c as a possible Fortran compiler, since by itself it
        cannot produce object code.

        * aclang.m4 (AC_PROG_F77): Remove f2c from the search list.
        * doc/autoconf.texi: Excise mentions of f2c in AC_PROG_F77 docs.

2000-05-26  Mark Elbrecht  <snowball3@bigfoot.com>

        Currently, AC_PROG_LN_S incorrectly reports yes with DJGPP. This
        is because the DJGPP `ln' emulates soft links for executables by
        generating a stub that in turn calls the real program.  This
        feature also works with nonexistent files like in the Unix
        spec. So `ln -s X conftestdata' will generate `conftestdata.exe'
        which will attempt to call 'X.exe'. But this feature only works
        for executables.  Fix it.

        * acspecific.m4 (AC_PROG_LN_S): Create a sample file and use it to
        test `ln -s'.

        AC_CANONICAL_SYSTEM was run, then the value of `$build' given by
        the user was saved into `$build_alias', and `$build' was
        normalized using `config.sub'.

        Now, let `--build' set `$build_alias' so that scripts with or
        without `AC_CANONICAL_BUILD' have the same semantics.  This allows
        to use `AC_CHECK_TOOL' without requiring `config.guess' and
        `config.sub' (which was bizarre anyway).

        * acgeneral.m4 (_AC_INIT_PARSE_ARGS): --build, --host and --target
        set `build_alias' etc.
        After the option handling, set host to $host_alias etc. for
        bugward compatibility.
        (AC_CANONICALIZE): Mutate into...
        (_AC_CANONICAL_SPLIT): this, which does not canonicalize, it just
        computes `$foo_os' etc.
        (_AC_CANONICAL_THING): Remove, too confusing.
        (AC_CANONICAL_BUILD): Adjust.
        Do not assign any value to `build_alias', just compute `build', and
        `build_{cpy, vendor, os}'.
        (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Likewise.
        (AC_CHECK_TOOL_PREFIX): Fire your rule when `$host_alias' is
        given, not when `$host != $build'.

        * acgeneral.m4 (sinclude): Fix typo.

        AC_PROG_F77, AC_PROG_F77_C_O, AC_PROG_GCC_TRADITIONAL here.
        Factor the comment documentation of AC_PROG_CC, AC_PROG_CXX,
        AC_PROG_F77.

2000-05-23  Akim Demaille  <akim@epita.fr>

        Modernize AC_EXEEXT and AC_OBJEXT.

        * acspecific.m4 (AC_EXEEXT, AC_OBJEXT): Use
        AC_COMPILE_IFELSE/AC_LINK_IFELSE and AC_LANG_PROGRAM instead of
        ad hoc code.
        Use `$ac_ext' instead of listing `.c', `.C' etc.

2000-05-22  Akim Demaille  <akim@epita.fr>

        Load the additions *before* running AC_INIT.
        This is important if you want to redefine AC_INIT or some of its
        sub macros (eeerk!), or if you want to use user defined macros
        before AC_INIT.
        Suggested by Didier Verna.

        * acgeneral.m4 (_AC_INIT): Don't include `acsite.m4' and
        `aclocal.m4'.

2000-05-22  Akim Demaille  <akim@epita.fr>

        Reading the ChangeLog revealed that the recent update of
        AC_FUNC_GETLOADAVG introduced a bug which already happened (see

        `--config-cache' and `-C'.

        (_AC_OUTPUT_SUBDIRS): Adjust.
        * doc/install.texi (Invoking configure): Rename the node as

        Document the new options.
        * doc/autoconf.texi (direntry): Huh?  What is this `aclocal' doing
        here?  Point to `Invoking configure'.
        (Cache Files): No need to document the disabling of the cache.

        * acgeneral.m4: Simplify all the unjustified `[\$]foo' into
        `\$foo', the quotes are needed only for `\$[1]', `\$[@]' etc.

2000-05-11  Akim Demaille  <akim@epita.fr>

        AC_CONFIG_SUBDIRS needs two lists: one, ac_subdirs_all, which
        contains all the possible subdirs for `--help=recursive', and
        another, `subdirs' which can be built dynamically for launching
        sub configurations.

        No longer use `autoupdate.m4', remove the dependencies.

        frozen files.
        * Makefile.am (nodistpkgdataDATA): Move `acversion.m4' to
        (distpkgdataDATA): here, so that all the `.m4' files are in the
        source hierarchy, not split across src and build.
        * acversion.m4.in: Update to today's standards.

        Suggested by Jim Meyering.

        * acgeneral.m4 (_AC_SHELL_TMPDIR): New macro.
        (_AC_OUTPUT_CONFIG_STATUS): Use it.
        Use more quoted here docs to improve readability.
        Compute `$me' and use it in the error messages.
        Define `$configure' and `$configure_args' to avoid continuously
        mixing the uses of `configure' and `config.status' evaluation in a
        single line.
        Define `$SHELL' and use it.
        Simplify all the unjustified `[\$]foo' into `\$foo', the quotes
        are needed only for `\$[1]', `\$[@]' etc.
        Replace all the uses of `ac_cs_root' with files in the tmp dir of
        `config.status'.
        Remove a few `rm' covered by the removal of the `$tmp' dir.
        Let `config.status' support `--debug'.
        (_AC_INIT_PREPARE): Avoid the leading space in `ac_configure_args'.
        * doc/autoconf.texi (Invoking config.status): Adjust.

2000-05-05  Jim Meyering  <meyering@lucent.com>

        * acgeneral.m4 (_AC_OUTPUT_CONFIG_STATUS): Set up traps to remove
        temporaries upon exit, too, not just upon receipt of signal.

2000-05-05  Akim Demaille  <akim@epita.fr>

        AC_CHECK_PROG macro fails if REJECT value is set under Digital
        Unix 4.0x and 5.0 because `"$@"' expands into an empty parameter
        (instead of nothing) when there are no positional parameters.
        From Nicolas Joly.

        * acgeneral.m4 (AC_CHECK_PROG, AC_CHECK_PROGS): Prefer
        `$$1' to `[$]$1', `$foo' to `[$]foo', `$[1]' to `[$]1', and
        `${1+"$[@]"}' to `"[$]@"'.

2000-05-04  Akim Demaille  <akim@epita.fr>

        AC_PREREQ understands `2.14a' as `2.141'.
        Reported by Didier Verna.

        AH_BOTTOM.

2000-05-03  Nicolas Joly  <njoly@pasteur.fr>

        * autoheader.sh (config_h): Sort the templates.
        Under NetBSD 1.4.1 /bin/sh `set' command does not return a sorted
        variables list.

2000-05-03  Akim Demaille  <akim@epita.fr>

        * tests/tools.m4 (autoheader): Don't pass `-l at_srcdir' to
        `autoheader', since `acconfig.h' is created in the build dir.
        There's one empty line less in `config.h.in' than before when
        using `acconfig.h'.

2000-05-03  Akim Demaille  <akim@epita.fr>

        Simplify the handling of `acconfig.h'.

        * autoheader.sh: No longer try to select the needed paragraphs of
        `acconfig.h', just dump everything into `config.h.in'.
        Implement support for `--warnings'.
        Warn the users that these auxiliary files are obsolete when `-W
        obsolete'.
        * doc/autoconf.texi (Invoking autoheader): Adjust.

2000-05-03  Akim Demaille  <akim@epita.fr>

        the list of $syms which are defined.
        * tests/tools.m4 (autoheader): New test.

2000-05-03  Akim Demaille  <akim@epita.fr>

        Rename the language FORTRAN77 as Fortran 77.

        * aclang.m4 (AC_LANG(FORTRAN77), AC_LANG_SOURCE(FORTRAN77),
        AC_LANG_PROGRAM(FORTRAN77), AC_LANG_CALL(FORTRAN77)): Rename as...
        (AC_LANG(Fortran 77), AC_LANG_SOURCE(Fortran 77),
        AC_LANG_PROGRAM(Fortran 77), AC_LANG_CALL(Fortran 77)): This.
        (AC_LANG_FORTRAN77): Adjust.

2000-05-03  Akim Demaille  <akim@epita.fr>

        Provide a macro to canonicalize a configuration name.
        Suggested by Ralf Corsepius.

        *  acgeneral.m4 (AC_CANONICALIZE): New macro.
        (_AC_CANONICAL_THING): Use it.


        Change the defaults for build, host, and target systems:
        build  defaults to `config.guess`.
        host   defaults to $build.
        target defaults to $host.
        Suggested by Mo DeJong, Pavel Roskin, Tom Tromey, Ian Lance
        Taylor, and many others.

        * acgeneral.m4 (_AC_INIT_PARSE_ARGS): Set `$build', `$host' and
        `$target' to nothing instead of NONE.
        (AC_CANONICAL_SYSTEM): AU_DEFUN'd as `AC_CANONICAL_TARGET'.
        (_AC_CANONICAL_THING): Use an explicit m4_case to set the defaults
        depending upon the THING.
        Implement the default values.
        (AC_CANONICAL_TARGET): Handle the `AC_ARG_PROGRAM' part
        `AC_CANONICAL_SYSTEM' used to provide.
        * doc/autoconf.texi: Adjust.


        When receiving an explicit argument, consider this is a default
        for --build, --host and --target (unless set).
        Some scripts might still depend on this historical syntax.
        Suggested by Alexandre Oliva.

        * acgeneral.m4 (_AC_INIT_PARSE_ARGS): Do that.
        (_AC_CANONICAL_THING): Drop the support of `$nonopt'.


        Documenting --build, --host and --target when configure does not
        handle them causes confusion.
        Suggested by Pavel Roskin.
        Nevertheless configure must not die on such an `unsupported'
        option: it does happen that people build an entire tree of
        packages, some of them expecting `--host' etc. some others not.
        Stressed by Tom Tromey and Ian Lance Taylor.

        * acgeneral.m4 (HELP_CANON): New diversion.
        (_AC_INIT_PARSE_ARGS): Don't document these options.
        (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
        Document your associated option.

2000-04-28  Akim Demaille  <akim@epita.fr>

        Don't double quote in AC_MSG_*.

        * acgeneral.m4 (_AC_SH_QUOTE): Don't double quote.  Escape the
        double quotes too.
        (_AC_ECHO_UNQUOTED): Don't double quote :).
        (_AC_ECHO, _AC_ECHO_N): Quote the call to _AC_SH_QUOTE.

        The autoheader chain needs to be adjusted.

        * acgeneral.m4 (AH_VERBATIM): Just pass two arguments to AH_OUTPUT
        instead of trying to build what `autoheader' needs: let it handle
        the format by itself.
        * autoheader.m4: Adjust.
        s,tmp/config.h,tmp/config.hin.

        The adjustment revealed that `autoconf --trace' is not robust to
        single quotes in its argument.

        * autoconf.sh: Fix this issue.
        Rename the escape `$*' as `$%'.  Implement `$@'.
        * doc/autoconf.texi: Adjust.

2000-04-28  Akim Demaille  <akim@epita.fr>

        mawk suffers a severe performance loss when using `sub' with a
        changing value.  On the `configure' script of the fileutils:
        mawk '{ sub (/foo/, foo++) }'                  -> 14s.
        mawk '{ if ($0 ~ /foo/) sub (/foo/, foo++) }'  -> 0.03s.
        mawk '{ sub (/foo/, foo) }'                    -> 0.03s.

        * autoconf.sh (task script, AWK script): Run `sub (__oline__,
        oline)' only in the lines that match `__oline__'.
        Suggested by Paul Eggert.

2000-04-28  Akim Demaille  <akim@epita.fr>

        * autoconf.sh (options handling::-W*): Strip two leading chars, not
        just one.

2000-04-20  Dave Love  <fx@gnu.org>

        * acspecific.m4 (AC_FUNC_MKTIME): Use AC_SUBST.

2000-04-12  Akim Demaille  <akim@epita.fr>

        Provide a fine grained control over autoconf's warnings.

        * acgeneral.m4 (AC_WARNING_IFELSE, _AC_DIAGNOSE, AC_DIAGNOSE):

        (AC_DEFUN_ONCE, AC_OBSOLETE, AC_BEFORE, AU_DEFUN, AC_PREREQ,
        AC_WARNING, AC_FATAL, AC_TRY_RUN): Use AC_DIAGNOSE.
        * autoconf.sh: Provide support for `--warnings', `-W'.
        * doc/autoconf.texi (Invoking autoconf): Adjust.
        (Reporting Messages): New section.

2000-04-12  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (_AC_INIT_HELP): Move --srcdir in the first
        section.
        Document --help=short and recursive.
        Split the `Directory' section into `Installation directories' for
        --prefix and --exec-prefix, and all the others into `Fine tuning
        of the installation directories'.
        In the latter, don't repeat `in DIR', the user understands, and it
        comes out better.
        Default for --exec-prefix is PREFIX.
        Reported by Kathryn Hargreaves.
        Move --host before --build.
        Fix a test on `$ac_init_help' which was not updated.

2000-04-11  Akim Demaille  <akim@epita.fr>

        Have `make check' succeed with CC=g++.

        * tests/atspecific.m4 (AT_TEST_MACRO): Don't check `env-after' if
        the file does not exist, which may happen when a `configure' exits
        brutally.
        * tests/semantics.m4 (AC_CHECK_MEMBERS, AC_CHECK_TYPES): ANSI C++
        forbids members named like their hosting struct, so don't do it.

2000-04-11  Akim Demaille  <akim@epita.fr>

        * autoscan.pl: Reindent using 2 spaces, not 4.
        Use `#' to denote Autoconf comments, not `dnl'.
        Put a few `\' here and there to avoid misfontification and
        misindentation.
        Use your base name when reporting errors.
        (parse_args::usage): Use $0, use the same order as the other
        executables.
        (parse_args): Don't dump `--help' on cmd line errors.

2000-04-11  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_PROVIDE_IF): Rename as...
        (AC_PROVIDE_IFELSE): this.  Change all callers.
        Spread the use of AC_PROVIDE_IFELSE, no macro should know how
        AC_PROVIDE names its internal variables.

2000-04-11  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4: Simplify all the `foo="$bar"' into `foo=$bar'.
        * acspecific.m4: Likewise.
        * aclang.m4: Likewise.

2000-04-11  Akim Demaille  <akim@epita.fr>

        Move obsolete macros' definitions out of the way.

        * doc/autoconf.texi (Old Macro Names): Rename as...
        (Old Macros): this.  Change the @table enumeration into a list of
        @defmac.
        (AC_CHECKING, AC_CHECK_TYPE, AC_COMPILE_CHECK, AC_C_CROSS,
        AC_DYNIX_SEQ, AC_HAVE_LIBRARY, AC_IRIX_SUN, AC_LINK_FILES,
        AC_OUTPUT, AC_OUTPUT_COMMANDS, AC_SCO_INTL, AC_VERBOSE,
        AC_XENIX_DIR): Move their descriptions into here.

        Disable caching by default, so as not to cause problems when
        newbies accidentally use a stale cache file.

        to disable caching by default.

2000-04-03  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (_AC_INIT_PARSE_ARGS): If any option waiting for a

        libexecdir, datadir, sysconfdir, sharedstatedir, localstatedir,
        libdir, includedir, oldincludedir, infodir, mandir, exec_prefix,
        prefix).  Fixes Autoconf 42.

2000-03-30  Steven G. Johnson  <stevenj@alum.mit.edu>

        Fix F77 name-mangling macros to work with cached values (so
        they don't break the second time you run configure).

        * aclang.m4 (AC_F77_NAME_MANGLING): Extract f77_case,
        f77_underscore from cache variable.
        (AC_F77_WRAPPERS): Get rid of ac_cv_f77_wrappers, it's useless.
        Simplify the nested case-esac into a single one.
        Simplify the documentation strings of CPP symbols.

        * acgeneral.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix the accumulation in
        CONFIG_HEADERS.

2000-03-31  Akim Demaille  <akim@epita.fr>

        autoconf.sh.
        * autoupdate.sh: Likewise.

2000-03-31  Steven G. Johnson  <stevenj@alum.mit.edu>

        * aclang.m4 (AC_F77_LIBRARY_LDFLAGS): bug fix in F77 test program
        (missing whitespace--F77 requires program statements to start in
        column 7).

2000-03-29  Akim Demaille  <akim@epita.fr>

        Rewrite the autoheader chain on top of `autoconf --trace'.

        * autoheader.m4: Dispatch the prototypes next to there AC_
        siblings.
        (AH_TEMPLATE, AH_VERBATIM): Move to...
        * acgeneral.m4: here.
        (AH_OUTPUT): New macro.

        the test above.

2000-03-29  Akim Demaille  <akim@epita.fr>

        silent.m4 depends upon the current quotation in m4, which changes
        if `-i' is used or not.

        * autoconf.sh (trace::silent.m4): Removed.
        (trace::run_m4_trace): Pass -Derrprint.

2000-03-29  Akim Demaille  <akim@epita.fr>

        Use `mktemp -d' when possible to create securely a tmp work dir.

        * autoconf.sh: Use it when possible to create the dir $tmp.
        Stop using variables for tmp files, use their names in $tmp.
        [install]: Use the new features of autoconf --trace.

2000-03-28  Akim Demaille  <akim@epita.fr>

        Probably all the versions of bash up to 2.04 fail on
          fnmatch ("/tmp", "[/\\\\]")
        The backslash must not be last.

        * acgeneral.m4 (_AC_INIT_HELP, AC_PATH_PROG, _AC_OUTPUT_FILES,
        _AC_OUTPUT_LINKS, _AC_OUTPUT_SUBDIRS): Always make `\\' be the
        first character in all the `[]' of `case' patterns.

2000-03-27  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (_AC_CHECK_TOOL_PREFIX): Rename back as
        AC_CHECK_TOOL_PREFIX since some packages rely on it.

2000-03-27  Akim Demaille  <akim@epita.fr>

        Move all the language dependent macros into aclang.m4.

        * aclang.m4: New file.
        * autoconf.m4: Include it.
        * autoheader.m4: Likewise.

2000-03-27  Akim Demaille  <akim@epita.fr>

        * autoconf.sh (trace): Let translate_awk do the whole translation
        from `$trace' to the m4 program.

2000-03-27  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_PACKAGE): Also define AC_PACKAGE_STRING.
        Use it here and there.

2000-03-25  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (_AC_CANONICAL_TARGET, _AC_CANONICAL_BUILD): Rename
        as (AC_CANONICAL_TARGET, AC_CANONICAL_BUILD), although internal,
        too much foreign code depends upon them.

2000-03-25  Akim Demaille  <akim@epita.fr>

        * autoconf.sh (translate_awk): `> "/dev/stderr"' is not portable
        to systems without a real /dev/stderr in the file system or if not
        using one of the three free awks.  Use
        print message | "cat >&2"
        ...
        END { close("cat >&2") }
        From Aharon Robbins.

2000-03-25  Akim Demaille  <akim@epita.fr>

        * autoheader.sh (checking completeness): Be ready to recognize
        patterns with a value, and spaces between `#' and the directive, e.g.
        # define FOO FIXME:
        Reported by John Fortin.

2000-03-25  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_RUN_IFELSE): New macro.
        (AC_TRY_RUN_NATIVE): Remove.
        (AC_TRY_RUN): Use AC_RUN_IFELSE, not AC_TRY_RUN_NATIVE.

2000-03-25  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_CHECK_LIB): Ah ah!  I recognized you, even
        masked: you are AC_TRY_LINK_FUNC.
        Fix quotation.
        (AC_SEARCH_LIBS): Use AC_SHELL_IFELSE.

2000-03-25  Akim Demaille  <akim@epita.fr>

        * tests/semantics.m4 (AC_TRY_LINK_FUNC, AC_CHECK_LIB): New tests.

2000-03-25  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_LANG_CALL, AC_LANG_CALL(C), AC_LANG_CALL(C++),
        AC_LANG_CALL(FORTRAN77)): New macros.
        (AC_TRY_LINK_FUNC): Use it.
        (AC_TRY_CPP): Argument was output twice.
        (AC_COMPILE_IFELSE, AC_LINK_IFELSE): Output $3 only if needed.

2000-03-25  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_TRY_COMPILER): Use AC_LINK_IFELSE.
        (AC_TRY_LINK_FUNC, AC_CHECK_LIB, AC_CHECK_FUNC): Don't check that
        the current language is C++ to output `extern "C"': the CPP
        condition is enough.

2000-03-25  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_LINK_IFELSE, AC_COMPILE_IFELSE): New macros.
        (AC_TRY_LINK, AC_TRY_COMPILE): Use them.
        (AC_CHECK_MEMBER, AC_COMPILE_CHECK, AC_CHECK_DECL,
        _AC_CHECK_TYPE_NEW): Adjust.
        * acspecific.m4 (AC_DECL_YYTEXT, AC_PATH_XTRA): Adjust.

2000-03-23  Steven G. Johnson  <stevenj@alum.mit.edu>

        * acspecific.m4 (AC_F77_NAME_MANGLING): Need to use
        AC_F77_LIBRARY_LDFLAGS when linking C and Fortran code.

2000-03-23  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_LANG_PROGRAM, AC_LANG_PROGRAM(C),
        AC_LANG_PROGRAM(C++), AC_LANG_PROGRAM(FORTRAN77)): New macros.

2000-03-23  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (_AC_INIT_PARSE_ARGS): Support --help={long, short,
        recursive}.
        (_AC_INIT_HELP): Propagate --help=recursive to CONFIG_SUBDIRS.
        Code stolen from...
        (AC_OUTPUT_SUBDIRS): s/ac_config_dir/ac_subdir/g.

2000-03-23  Lars J. Aas  <larsa@sim.no>

        * libm4.m4 (m4_do): New macro.

2000-03-21  Akim Demaille  <akim@epita.fr>

        Provide a language independent means to generate language specific
        programs.

        * acgeneral.m4 (_AC_LANG_DISPATCH): New macro.
        (AC_LANG): Use it.
        (AC_LANG_SOURCE, AC_LANG_SOURCE(C), AC_LANG_SOURCE(C++),
        AC_LANG_SOURCE(FORTRAN77)): New macros.
        (AC_TRY_COMPILER, AC_EGREP_CPP, AC_TRY_RUN_NATIVE): Use
        AC_LANG_SOURCE.

2000-03-21  Akim Demaille  <akim@epita.fr>

        Fix a bug: some macros (e.g., AC_REVISION, AC_COPYRIGHT etc.) can
        be used before AC_INIT, but they do require it.  But then, the
        argument of the explicit AC_INIT call is lost.

        * acgeneral.m4 (AC_CONFIG_SRCDIR): New macro.
        (_AC_INIT_SRCDIR): Adjust.
        (_AC_INIT): Pass your argument to AC_CONFIG_SRCDIR.

2000-03-21  Akim Demaille  <akim@epita.fr>

        * tests/semantics.m4 (AC_PATH_PROG, AC_PATH_PROGS): New tests.

2000-03-21  Akim Demaille  <akim@epita.fr>

        Start the language support overhaul: Introduce AC_LANG().

        * acgeneral.m4 (AC_LANG): Renamed as _AC_LANG_CURRENT.
        (AC_LANG, AC_LANG(C), AC_LANG(C++), AC_LANG(FORTRAN77)): New
        macros.
        (AC_LANG_C, AC_LANG_CPLUSPLUS, AC_LANG_FORTRAN): AU_DEFUN'ed.
        Adjust all callers.
        * acspecific.m4 (AC_F77_NAME_MANGLING): Remove the exceeding
        AC_LANG_RESTORE.
        * tests/Makefile.am (FILTER_MACROS): Add AC_LANG.

2000-03-21  Akim Demaille  <akim@epita.fr>

        Speed ups.

        * libm4.m4 (m4_append, m4_list_append): Use m4_define, not define.
        On my machine the former implementation takes 4mn 40s to run the
        test suite.  Using m4_define leads to 4mn 15s.
        * acgeneral.m4 (_AC_SUBST): Use AC_EXPAND_ONCE (which uses
        m4_define, not define).  4mn.
        (_AC_DIVERT): Don't use m4_case.  Starting from those 4mn, if you
        just move NORMAL* first in m4_case, the test suite is run in 3mn.
        If instead of using m4, you use an `associative array' plus a
        wrapper (current implementation), it falls to 2mn.

2000-03-21  Akim Demaille  <akim@epita.fr>

        * tests/tools.m4 (autoconf --trace): New test.

2000-03-21  Akim Demaille  <akim@epita.fr>

        * autoconf.sh (task trace): Pipe the output of the first m4 into
        the second one, instead of saving to a tmp file, so that we can
        trace endless configure.in expansion.

2000-03-21  Akim Demaille  <akim@epita.fr>

        Uniform idioms.

        * acgeneral.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
        _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Prefer
        for i in : $is; do test $i = : && continue
        over
        for i in .. $is; do if test $i != ..; then

2000-03-21  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (_AC_INIT_PREPARE, _AC_INIT_PARSE_ARGS): Move more
        initializations to...
        (_AC_INIT_DEFAULTS): here.

2000-03-21  Akim Demaille  <akim@epita.fr>

        Give a means to compute `srcdir' earlier in configure.

        * acgeneral.m4 (_AC_INIT_SRCDIR): New macro, pulled out from...
        (_AC_INIT_PREPARE): No longer compute `srcdir'.
        (_AC_INIT): Use _AC_INIT_SRCDIR.
        (AC_INIT): Don't forget to pass the argument to _AC_INIT.

2000-03-20  Jim Meyering  <meyering@lucent.com>

        * acspecific.m4 (AC_SYS_LONG_FILE_NAMES): Don't test for existence
        of $ac_xdir.  Not only is `test -e' not portable, but the test isn't
        necessary at all;  the following mkdir ends up accomplishing the
        same goal.  Suggestion from Alexandre Oliva.

        * acgeneral.m4 (_AC_INIT_PREPARE_ENVIRONMENT) [setting IFS]: Be careful
        to use space, tab and new line, in precisely that order.

2000-03-20  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_OUTPUT_SUBDIRS): Rename as _AC_OUTPUT_SUBDIRS.
        No argument, use AC_LIST_SUBDIRS.
        Adjust callers.

2000-03-20  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Double quote the head
        of the help snippet.

2000-03-20  Akim Demaille  <akim@epita.fr>

        Give an identity to `configure' scripts.

        * acgeneral.m4 (AC_PACKAGE): New macro.
        (_AC_COPYRIGHT_SEPARATOR): Remove.
        (AC_COPYRIGHT): Adjust.
        (_AC_INIT_HELP, _AC_INIT_VERSION): Name the package you configure
        when you want.
        (_AC_INIT): Adjust.
        * configure.in (AC_PACKAGE): Add.

2000-03-20  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4: Formatting changes.

2000-03-20  Akim Demaille  <akim@epita.fr>

        Don't rely on RS = "\0" to swallow the whole input as a single
        record, this is not portable: mawk and nawk understand it as RS =
        "".  gawk understands it as expected.

        * autoconf.sh (translate_awk::BEGIN): No longer change RS.
        (translate_awk::body): Move to the END.
        Instead, accumulate the input in `request'.

2000-03-20  Akim Demaille  <akim@epita.fr>

        * doc/autoconf.texi (Testing Values and Files): Be a subsection of
        `Portable Shell Programming'.
        (Shell Substitutions, Limitations of Usual Tools): New subsections.

2000-03-17  Akim Demaille  <akim@epita.fr>

        Use a single tool to reformat the raw `configure' script output by
        m4.
        Suggested by Paul Eggert.

        * autoconf.sh: Stop playing with 2 seds and an AWK to finalize
        `configure', a single AWK program is enough.

2000-03-17  Akim Demaille  <akim@epita.fr>

        In Autoconf 2.13, although AC_OUTPUT_COMMANDS did double quote its
        arguments, AC_OUTPUT arguments 2 and 3 were not!  Currently,
        AC_OUTPUT over quotes too: stop that.
        Reported by Martin Buchholz.

        * doc/autoconf.texi (Output): Don't expand on the ternary
        AC_OUTPUT.
        * acgeneral.m4 (AC_OUTPUT): Don't over quote $2 and $3.

2000-03-17  Joseph S. Myers  <jsm28@cam.ac.uk>

        * acspecific.m4 (AC_SYS_LONG_FILE_NAMES): Security fixes: create
        the temp files in a private temporary directory, not directly in
        TMPDIR.

2000-03-17  Akim Demaille  <akim@epita.fr>

        Install the IFS we need once for all.

        * acgeneral.m4 (_AC_INIT_PREPARE_ENVIRONMENT): New macro.
        Handle the NLS envvars, and IFS.
        (_AC_INIT_PREPARE): Use it, no longer set the NLS envvars.
        (_AC_WHICH_A, AC_PATH_PROG): Rely on the default IFS.
        * acspecific.m4 (AC_PROG_INSTALL, AC_FUNC_SELECT_ARGTYPES):
        Likewise.

2000-03-17  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_TRY_CPP, AC_EGREP_CPP, AC_TRY_COMPILE,
        AC_TRY_LINK, AC_TRY_RUN_NATIVE): Simplify the removal of the
        contest files: don't remove them before running the actions, just
        remove them at the end of the macro.

2000-03-16  Akim Demaille  <akim@epita.fr>

        * acspecific.m4 (AC_FUNC_SELECT_ARGTYPES): Use
          : ${foo='some words'}
        not
          : ${foo=some words}
        since this is not portable: Digital Unix v5.0: `bad substitution'.
        From Nicolas Joly.

2000-03-16  Lars J. Aas  <larsa@sim.no>

        * libm4.m4 (m4_assert, m4_shiftn): New macros.
        (m4_case,m4_match): Rewrite to use m4_shiftn (for readability reasons).
        (m4_for): Add the STEP argument and some argument-verifying asserts.
        (m4_split): Correct spaces to tabulator in regexp.

2000-03-15  Akim Demaille  <akim@epita.fr>

        Revamp AC_FUNC_SELECT_ARGTYPES.

        * acspecific.m4 (AC_FUNC_SELECT_ARGTYPES): Use a single cache
        variable instead of three.
        Use AC_CACHE_CHECK.
        Shorten the name of the var loops, they are no longer cached.
        Include sys/types.h unconditionally.
        `select' returns an int, fixes Autoconf/46.
        Don't display parens in the user messages.

2000-03-14  Akim Demaille  <akim@epita.fr>

        * autoheader.sh: Use run_m4f, not run_m4.

2000-03-14  John David Anglin  <dave@hiauly1.hia.nrc.ca>

        * tests/actest.m4 (AC_ENV_SAVE): Don't consider RANDOM and LINENO
        which some shells update.  At least ksh on HP-UX 10.20 and sh on
        IRIX 6.5 do change their `RANDOM' even if `read' via `set'.

2000-03-14  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_ARG_ENABLE, AC_ARG_WITH): No use for @%:@ here,
        no need to over quote $1 in the comments.

2000-03-14  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4: Replace some ifelse with ifval or m4_default, or
        even nothing when not needed.
        * acspecific.m4: Likewise.

2000-03-14  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (_AC_INIT_PREPARE): Insert the Autoconf version in
        config.log, and the command line which ran configure.
        Kill a couple of useless quote around dollars.

2000-03-14  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (_AC_INIT_PREPARE): Kill a changequote in the
        building of `ac_configure_args'.

2000-03-14  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_DIVERT): Rename _AC_DIVERT.
        (AC_DIVERT): New macro.
        Spread its use where better than a pair of AC_DIVERT_PUSH/POP.

2000-03-14  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (_AC_INIT_BINSH): Remove, useless now that...
        (AC_REVISION): Require AC_INIT, not _AC_INIT_BINSH.
        (AC_INIT): Do what _AC_INIT_BINSH used to.
        Don't require _AC_INIT_VERSION, just call it.
        Rename as _AC_INIT.
        (AC_INIT): New macro, single expansion wrapper around _AC_INIT.
        (_AC_COPYRIGHT_SEPARATOR): New.
        (AC_COPYRIGHT): Use it.
        Require AC_INIT, not _AC_INIT_VERSION.
        * doc/autoconf.texi (Versions): Promote as first section of
        `Setup'.
        Rename as `Notices'.
        Document AC_COPYRIGHT.
        Don't give false reasons for placing AC_REVISION before AC_INIT,
        the place no longer matters.

2000-03-14  Akim Demaille  <akim@epita.fr>

        * autoconf.sh (trace_m4::smash): Double quote, we don't want the
        result to be evaluated.

2000-03-14  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4: s/@%:@line __oline__/#line __oline__/g. __oline__
        is not a macro, so there is just no use in avoiding `#'.

2000-03-14  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (_AC_OUTPUT_CONFIG_STATUS): When there were no
        CONFIG_FILES, we had to expand _AC_OUTPUT_FILES into the KILL
        diversion, because it is AC_OUTPUT_FILES which undiverted the
        AC_SUBST sed script at its proper place, otherwise it would have
        been undiverted at the end of `configure', leading to an sh syntax
        error.
        Now that we no longer use a diversion, we don't need to call
        AC_OUTPUT_FILES if useless.
        (AC_OUTPUT_FILES): Rename as _AC_OUTPUT_FILES.
        (AC_OUTPUT_LINKS): Rename as _AC_OUTPUT_LINKS.

2000-03-14  Akim Demaille  <akim@epita.fr>

        AC_ARG_PROGRAM must not be expanded twice, which is likely since
        Automake calls it, and usually users do too.  If it happens,
        `--program-prefix=g' actually prepend two (or more) `g'.

        * acgeneral.m4 (AC_DEFUN_ONCE): New macro.
        (AC_ARG_PROGRAM): AC_DEFUNed_ONCE.  Or is it AC_DEFUN_ONCE'd? :).
        No longer AC_EXPAND_ONCE the help string, the macro itself is
        expanded at most once.
        Rename the here-doc tag EOF_SED as EOF.

2000-03-14  Akim Demaille  <akim@epita.fr>

        Get rid of the ICMDS diversion.

        * acgeneral.m4 (AC_DIVERT): Remove ICMDS.
        (_AC_OUTPUT_COMMANDS_INIT): New growing string.
        (_AC_CONFIG_COMMANDS_INIT, _AC_OUTPUT_CONFIG_STATUS): Adjust.

2000-03-14  Akim Demaille  <akim@epita.fr>

        Introduce AC_SUBST(VAR, VAL).

        * acgeneral.m4 (_AC_INIT_PARSE_ARGS): Stop global double quoting,
        failed experiment.
        Merge all the var=val AC_SUBST(var) into AC_SUBST(var, val).
        (AC_SUBST): Implement support for 2nd arg.
        * doc/autoconf.texi (Setting Output Variables): Adjust.

2000-03-13  Akim Demaille  <akim@epita.fr>

        Simplify the diversions naming system.
        Suggested by Alexandre Oliva and Lars J. Aas

        * libm4.m4 (ifndef): New macro.
        * acgeneral.m4 (AC_DIVERT): New macro, maps a diversion name to
        its value.  The diversions now have a short name, e.g., `NOTICE',
        instead of the former macros which had long names, e.g.,
        `AC_DIVERSION_NOTICE'.
        (AC_DIVERT_PUSH): Adjust.
        (AC_DIVERT_POP): Use ifndef.
        (AC_DIVERSION_CURRENT): Rename as `AC_DIVERT_DIVERSION' to stay
        within the `AC_DIVERT' name domain.
        Adjust all callers.
        * acspecific.m4: Adjust all callers.

2000-03-13  Akim Demaille  <akim@epita.fr>

        * doc/autoconf.texi (Invoking autoconf): Update documentation of
        `autoconf --trace'.

2000-03-13  Akim Demaille  <akim@epita.fr>

        * autoconf.sh (tmpbase): New var.  Adjust trap code and other tmp
        file names.
        (translate_awk::BEGIN): Set RS to "\0" so that the whole file be a
        single record.
        (translate_awk::trans): Convert from array to function.
        (translate_awk::error): New function.
        (translate_awk::main action): Implement support for ${sep}@ and
        ${sep}*.  Use trans() and error().
        (translate_awk): Don't put space before user functions call, it is
        not portable.
        Remove trailing `;', this is not C :).
        (task trace): Quote `$traces' when you eval it, to protect the
        white spaces.
        Propagate `translate_awk' failures to `autoconf.sh'.
        Translate the quadrigraphs.

2000-03-13  Akim Demaille  <akim@epita.fr>

        Trap on 0 is not executed when `exit' is called without argument.

        * autoheader.sh (trap 1 2 13 15): s/exit/exit $?/.
        * autoconf.sh: Likewise.
        Remove translate_awk too.
        * autoupdate.sh: Likewise.
        Handle `--debug'.

2000-03-13  Akim Demaille  <akim@epita.fr>

        More uniform style in scripts.

        * autoheader.sh: s/-eq/=/.
        Uniform ordering of variable initializations, option handling.
        Don't use quotes where useless (foo=$1, not foo="$1").
        Propagate `run_m4' and `run_m4f'.
        Use `$0' in --help.
        * autoconf.sh: Likewise.
        * autoreconf.sh: Likewise.
        * autoupdate.sh: Likewise.
        * ifnames.sh: Likewise.
        * autoupdate.m4: Small bug: at the end `dnl' is disabled, so use
        `m4_dnl'.

2000-03-13  Akim Demaille  <akim@epita.fr>

        `autoconf --trace': faster.

        * autoconf.sh (initialization): New var, new option.
        (option loop): When you need an arg, make sure there is one.
        (run_m4f): New var, which content is that of the former...
        (run_m4): Don't use m4 frozen state files.
        Change all callers.
        Don't pass AC_LOCALDIR, not documented, and unused.
        (task trace): Honor `--verbose' and `--initialization'.
        (globally): Send `--verbose' messages in stderr.
        Fix random typos.

2000-03-13  Akim Demaille  <akim@epita.fr>

        * acspecific.m4 (AC_PROG_BINSH): Removed.

2000-03-13  Akim Demaille  <akim@epita.fr>

        Start revamping `autoconf --trace'.

        * autoconf.sh (debug): New var, new option.
        Adjust the trap code.
        (task trace): Instead of decoding `m4 --trace' with sed, decode it
        with m4 itself.
        ($silent_m4): New file, which disables m4's `errprint'.
        ($trace_m4): New file.  Logistic for the m4 which is in charge of
        decoding the traces of the first.
        ($translate_awk): Transform a user trace request into $trace_m4
        code.

2000-03-10  Akim Demaille  <akim@epita.fr>

        Multiple `-e' to egrep are not portable.  On IRIX 6.5 and Solaris
        2.5.1 only the last one is honored:
          > printf "foo\nbar\n" | egrep -e 'foo' -e 'bar'
          bar
          > printf "foo\nbar\n" | egrep -e 'bar' -e 'foo'
          foo
        Reported by Nicolas Joly.
        An alternative would have been to use `sed', unfortunately
        alternation is not portable.

        * tests/actest.m4 (join): New macro.
        (AC_ENV_SAVE): Join the egrep patterns into a single big one.
        * tests/Makefile.am (EGREP_EXCLUDE): Rename as FILTER_MACROS.
        Join the egrep patterns into a single big one.

2000-03-10  Jim Meyering  <meyering@lucent.com>

        * acgeneral.m4 (_AC_CHECK_TOOL_PREFIX): Correct typos in definition:
        add `_' prefix to make the function name match comments and existing
        uses.  Remove leading prefix from _AC_CANONICAL_HOST.

2000-03-09  Ossama Othman  <ossama@debian.org>

        * acspecific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Added some missing
        headers if they exist (needed for some missing prototypes) and
        corrects the signal handler prototype/definition.  The signal
        handler prototype is now prepended with an `extern "C"' for C++
        compilers since some platforms explicitly require an `extern "C"'
        signal handler.

2000-03-08  Akim Demaille  <akim@epita.fr>

        * autoheader.m4 (autoheader::AC_CHECK_HEADERS_DIRENT): Rename as
        (autoheader::_AC_CHECK_HEADERS_DIRENT): to cope with the new name
        of the autoconf:: macro.
        Fixes autoconf/119, reported by Raja R Harinath.

2000-03-08  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_PATH_PROG, AC_OUTPUT_FILES, AC_OUTPUT_SUBDIRS):
        Fix quotation problems in DOS path handling.

2000-03-08  Franz Sirl  <Franz.Sirl-kernel@lauterbach.com>

        * acspecific.m4 (AC_FUNC_MMAP, AC_FUNC_ALLOCA): Make them C++
        safe: include the right headers, cast the allocations etc.

2000-03-08  Akim Demaille  <akim@epita.fr>

        The argument of AC_COPYRIGHT should be plain text, not an sh
        comment.

        * libm4.m4 (m4_quote): s/$@/$*/.
        * acgeneral.m4 (AC_COPYRIGHT): Prepend `# ' to the lines that go
        on the top of `configure'.  Actually, prepend `@%:@ ' so that
        there are as many evaluations on both sides.
        (_AC_INIT_VERSION): No longer strip `# '.

2000-03-08  Akim Demaille  <akim@epita.fr>

        * tests/Makefile.am (all-local): Remove.  It wastes time to have
        testsuite rebuilt each time an ac*.m4 file changes.  It is enough
        to build it for each `make check'.

2000-03-08  Akim Demaille  <akim@epita.fr>

        Leave a diversion exclusively for Copyright notices.

        * acgeneral.m4 (AC_DIVERSION_DEFAULTS): New diversion number.
        (_AC_INIT_NOTICE): Move definition of `ac_includes_default' from
        here...
        (_AC_INIT_PREPARE): to here.
        (_AC_INIT_NOTICE): Play with your diversion yourself, don't let
        (AC_INIT): do it for you.
        (_AC_INIT_DEFAULTS): New macro.
        (AC_INIT): Use it.

2000-03-08  Akim Demaille  <akim@epita.fr>

        Provide a means to specify more Copyright information in
        `configure'.  And after all, it suits to `configure --version' too.

        * acgeneral.m4 (AC_DIVERSION_DEFAULTS, AC_DIVERSION_INIT_PREPARE):
        New diversion numbers.
        (AC_DIVERSION_INIT): Rename as...
        (AC_DIVERSION_INIT_PARSE_ARGS): this.
        (AC_DIVERT_POP): Instead of going into wild endless loops when
        there are more pops than pushes, die with dignity.
        (AC_COPYRIGHT): New macro.
        (_AC_INIT_NOTICE): Move definition of `ac_includes_default' from
        here...
        (_AC_INIT_PREPARE): to here.
        (_AC_INIT_NOTICE): Remove.
        (AC_INIT): Use it to install Autoconf's Copyright.
        (_AC_INIT_DEFAULTS): New macro.
        (AC_INIT): Use it.
        (AC_PREFIX_DEFAULTS): Dump in AC_DIVERSION_DEFAULTS.
        (_AC_INIT_PARSE_ARGS): Dump in AC_DIVERSION_INIT_PREPARE.

2000-03-08  Akim Demaille  <akim@epita.fr>

        We don't need _AC_ARG_*_HELP_PROLOGUE.

        * acgeneral.m4 (AC_EXPAND_ONCE): AC_PROVIDE yourself, in case
        there is no AC_DEFUN associated with the text to expand.
        (_AC_ARG_ENABLE_HELP_PROLOGUE, _AC_ARG_WITH_HELP_PROLOGUE,
        _AC_ARG_VAR_HELP_PROLOGUE): Remove, instead...
        (AC_ARG_ENABLE, AC_ARG_WITH, AC_ARG_VAR): do it yourself.

2000-03-08  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (_AC_INIT_PARSE_ARGS): Fix copy n' paste typos in
        `--with-*', `--without-*' and `*' decoding.
        Reported by Raja R Harinath.
        Fixes autoconf/118.

2000-03-08  Akim Demaille  <akim@epita.fr>

        Don't dump AC_ARG_PROGRAM help messages if not used.

        * acgeneral.m4 (_AC_INIT_HELP): Don't.
        (AC_ARG_PROGRAM): Do.

2000-03-08  Akim Demaille  <akim@epita.fr>

        Don't dump X help messages when `configure' does not check for X.

        * acgeneral.m4 (_AC_INIT_HELP): Don't dump X help messages.
        * acspecific.m4 (AC_PATH_X): Do it.

2000-03-08  Akim Demaille  <akim@epita.fr>

        No longer rely on /bin/sh to compose the optional parts of
        `configure --help'.

        * acgeneral.m4 (AC_DIVERSION_HELP_BEGIN, AC_DIVERSION_HELP_ENABLE,
        AC_DIVERSION_HELP_WITH, AC_DIVERSION_HELP_VAR,
        AC_DIVERSION_HELP_END): New diversion numbers.
        (AC_EXPAND_ONCE): New macro.
        (AC_PROVIDE_IF): New macro.
        (AC_BEFORE, AC_REQUIRE): Use it.
        (AC_REQUIRE): Don't use indir.
        (_AC_ARG_ENABLE_HELP_PROLOGUE, _AC_ARG_WITH_HELP_PROLOGUE,
        _AC_ARG_VAR_HELP_PROLOGUE): New macros.
        (AC_ARG_ENABLE, AC_ARG_WITH, AC_ARG_VAR): Expand once the
        _HELP_PROLOGUE macro which corresponds.
        (_AC_INIT_HELP): Adjust to AC_DIVERSION_HELP_BEGIN and
        AC_DIVERSION_HELP_END.
        (_AC_INIT_NOTICE, _AC_INIT_HELP): Remove the sh code which handled
        the optional help strings.

2000-03-08  Akim Demaille  <akim@epita.fr>

        AC_OUTPUT_COMMANDS no longer uses a diversion.

        * acgeneral.m4 (AC_DIVERSION_CMDS): Removed.
        (_AC_OUTPUT_CONFIG_STATUS): Don't undivert it.

2000-03-08  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (_AC_INIT_PARSE_ARGS): Fix quoted/non quoted here
        document problems.

2000-03-08  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_INIT_BINSH, AC_INIT_NOTICE, AC_INIT_PREPARE):
        Rename as...
        (_AC_INIT_BINSH, _AC_INIT_NOTICE, _AC_INIT_PREPARE): this.
        All callers adjusted.

2000-03-08  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_INIT_PARSE_ARGS): Rename as...
        (_AC_INIT_PARSE_ARGS): this.
        Move the display of help and version strings to...
        (_AC_INIT_HELP, _AC_INIT_VERSION): here.
        (AC_INIT): Adjust.  Also, fix quotation.

2000-03-08  Akim Demaille  <akim@epita.fr>

        Some tests are failing with srcdir != builddir, because they can't
        find config.guess, install-sh etc.
        Reported by Erez Zadok.

        * tests/atspecific.m4 (AT_TEST_MACRO): Set AC_CONFIG_AUX_DIR to
        top_srcdir in configure.in, and pass the value of top_srcdir to
        configure.

2000-03-08  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_ARG_ENABLE, AC_ARG_WITH, AC_PATH_PROG,
        AC_PATH_PROGS, AC_PATH_TOOL, AC_CHECK_TOOL, AC_PREFIX_PROGRAM,
        AC_EGREP_CPP, AC_TRY_LINK, AC_COMPILE_CHECK, AC_TRY_RUN_NATIVE):
        Use ifval instead of ifelse.

2000-03-07  Mark Elbrecht  <snowball3@bigfoot.com>

        Support absolute DOS-style paths.

        Any character before the colon is accepted because network drives
        can be assigned characters outside the [a-zA-Z] range. DOS-style
        relative paths (?:foo/bar) are also considered absolute for
        Autoconf's purposes since the path '../?:foo/bar' is invalid.

        * acgeneral.m4 (AC_OUTPUT_FILES): Treat DOS-style paths (?:*') as
        absolute.
        (AC_OUTPUT_SUBDIRS): Likewise.
        (AC_PATH_PROG): Make pattern for matching DOS-style paths the same
        as that used in AC_OUTPUT_FILES and AC_OUTPUT_SUBDIRS.

2000-03-06  Akim Demaille  <akim@epita.fr>

        * tests/atspecific.m4 (m4_match): Remove, no longer used.

2000-03-04  Jim Meyering  <meyering@lucent.com>

        * autoheader.sh: Use `rm -f', not just `rm' when removing temporaries.
        Preserve exit status in trap handler.
        Based on suggestions from Paul Eggert.

2000-03-03  Paul Eggert  <eggert@twinsun.com>

        Move the quadrigraphs out of the user name space.

        * acgeneral.m4: 's/\@BKL@/@<:@/g', 's/\@BKR@/\@:>@/g',
        's/\@DLR@/\@S|@/g', 's/\@PND@/@%:@/g'.

2000-03-03  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (_AC_WHICH_A): New macro.

        * tests/semantics.m4: Test AC_CHECK_PROG.
        * tests/Makefile.am (EGREP_EXCLUDE): Add /AC_CHECK_PROGS?/.

2000-03-02  Russ Allbery  <rra@stanford.edu>

        * autoscan.pl (parse_args): Add support for -m <macrodir>.

2000-03-02  Akim Demaille  <akim@epita.fr>

        The whole family supports -V = --version.

        In addition, don't dump --help on invalid options.
        * doc/autoconf.texi: Adjusted.
        * doc/install.texi: Likewise.

2000-03-02  Lars J. Aas  <larsa@sim.no>

2000-03-02  Akim Demaille  <akim@epita.fr>

        * acspecific.m4 (AC_PATH_X_DIRECT): Moved all the shell variable
        into the ac_ name space.
        Reported by Nicolas Joly.

2000-03-02  Akim Demaille  <akim@epita.fr>

        * acspecific.m4: Move some macros to a better place.

2000-03-02  Akim Demaille  <akim@epita.fr>

        Internal macros are named `_AC_'.

        * acgeneral.m4 (AC_CANONICAL_TARGET, AC_CANONICAL_BUILD,

        Prepend `_' to their names.
        * acspecific.m4 (AC_CHECK_HEADER_DIRENT, AC_CHECK_HEADERS_DIRENT,
        AC_PATH_X_XMKMF, AC_PATH_X_DIRECT): Prepend `_' to their names.

2000-03-02  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4: Formatting changes.
        * acspecific.m4: Likewise.

2000-03-01  Akim Demaille  <akim@epita.fr>

        The empty regexp cannot be portably used in egrep's alternation.
        For instance with Digital Unix v5.0:

2000-03-01  Lars Hecking  <lhecking@nmrc.ucc.ie>

        * acspecific.m4 (AC_PATH_XTRA): On LynxOS 3.0.1/i386,

        * config.sub: Likewise.

2000-03-01  Akim Demaille  <akim@epita.fr>

        Test suite: instead of using a full list of the AC macros and an
        AT macro with selects which are the AC macros to test, just
        produce the list of the AC macros we want to test.

        * tests/atspecific.m4 (TEST_MACRO): Removed.
        * tests/Makefile.am (EGREP_EXCLUDE): New variable, performing the
        selection TEST_MACRO used to do.
        (macros.m4): Use it.  Use AT_TEST_MACRO, not TEST_MACRO.  Check
        also AU macros.

2000-03-01  Akim Demaille  <akim@epita.fr>

        * doc/autoconf.texi: Tune the use of quotes, add missing
        @noindents, remove dead FIXME:s, promote #if ! over #ifndef,
        simplify duplicated text.

2000-03-01  Akim Demaille  <akim@epita.fr>

        Export the knowledge on disabling echo's trailing new line.

        * acspecific.m4 (AC_PROG_ECHO_N): Rename as...
        (_AC_PROG_ECHO): this.
        Set ECHO_N, ECHO_C, ECHO_T instead of ac_n, ac_c and ac_t.
        All dependencies changed.
        * doc/autoconf.texi (Preset Output Variables): Document ECHO_C,
        ECHO_N and ECHO_T.
        * m4/atconfig.m4 (fp_PROG_ECHO): Removed.

        aclocal.
        From Nicolas Joly.

2000-02-22  Pavel Roskin  <pavel_roskin@geocities.com>

        * configure.in (HELP2MAN): Specify the third argument of

2000-02-21  Akim Demaille  <akim@epita.fr>

        * tests/tools.m4 (syntax.sh): The logic of the previous patch was
        twisted.  Fix it so that it performs what claims the entry below.
        From Nicolas Joly.

2000-02-21  Akim Demaille  <akim@epita.fr>

        * tests/tools.m4 (syntax.sh): Exit 1 if you managed to kill the
        child, since it means `/bin/sh -n' went loopy.

2000-02-18  Akim Demaille  <akim@epita.fr>

        Some `diff' refuse to diff with /dev/null, such as Tru64's.
        Reported by Nicolas Joly.

        * tests/atgeneral.m4 (empty): New dummy file.
        Changed various `diff /dev/null' as `diff empty'.

2000-02-18  Akim Demaille  <akim@epita.fr>

        * tests/atspecific.m4 (TEST_MACRO): Don't run AC_PATH_TOOL and
        AC_PATH_PROG.

2000-02-18  Akim Demaille  <akim@epita.fr>

        * tests/atgeneral.m4 (at_diff): Don't use `cmp -s', on DOS it
        differentiate between Unix and DOS EOL. `diff' does not.
        Reported by Eli Zaretski.
        Also, be ready to use a diff that does not support `-u'.

2000-02-18  Akim Demaille  <akim@epita.fr>

        * tests/tools.m4 (Syntax of the scripts): Be robust to shells that
        never return on some `/bin/sh -n foo.sh'.
        Reported by Nicolas Joly.

2000-02-17  Akim Demaille  <akim@epita.fr>

        Move the documentation into doc/.
        Some CVS tricks were used so that history is kept in both the top
        directory, and in doc/.

        * doc/Makefile.am: New file.
        * Makefile.am: Adjusted.
        * configure.in: Adjusted.

2000-02-17  Akim Demaille  <akim@epita.fr>

        Fix the `missing dummy.in' reported by the test suite.
        Reported by Erez Zadok.

        * tests/torture.m4 (config.status under extreme conditions):
        Reorganized.  Because files required by this test were created
        outside the pair AT_SETUP/AT_CLEANUP, when the test fails and
        autotest extracts this test, the `debug' script does not contain
        the files it needs.  Now AT_SETUP/AT_CLEANUP encloses the full
        auto contained section.

2000-02-16  Akim Demaille  <akim@epita.fr>

        Reported by Franc,ois Pinard and Rainer Orth.

        * autoreconf.sh: Removed spurious `;;'.
        Formatting changes.
        * tests/tools.m4 (Syntax of the scripts): Run `sh -n' on all the
        shell scripts.

2000-02-15  Akim Demaille  <akim@epita.fr>

        * autoconf.sh (options handling): --v* of --version was shadowing
        --verbose.

2000-02-11  Akim Demaille  <akim@epita.fr>

        * tests/torture.m4: Nuke the trailing space in defs.

2000-02-11  Akim Demaille  <akim@epita.fr>

        * tests/atspecific.m4: Really added to the CVS repository.

2000-02-11  Akim Demaille  <akim@epita.fr>

        Don't use `cat -s' to single out new-lines, it is not portable.
        Also remove trailing blanks.

        * tests/Makefile.am (testsuite): Use sed instead of cat.
        * tests/torture.m4: No longer check for a trailing space.
        * autoconf.sh: Likewise.

2000-02-10  Akim Demaille  <akim@epita.fr>

        * tests/actest.m4 (AC_ENV_SAVE): OpenBSD-2.3's /bin/sh defines an
        envvar SECONDS which does change with time.
        KMEM_GROUP is set by AC_FUNC_GETLOADAVG.
        Reported by Volker Borchert.

2000-02-10  Akim Demaille  <akim@epita.fr>

        * tests/Makefile.am (macros.m4): Better regex to build `macro'.
        Depend upon acgeneral.m4.

2000-02-10  Akim Demaille  <akim@epita.fr>

        * autoheader.sh: Remove the duplicate trap code.

2000-02-10  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_OUTPUT): When dispatching your arguments, use
        ifval, not ifset!
        Dispatch actions to AC_CONFIG_COMMANDS not AC_OUTPUT_COMMANDS, to
        avoid unneeded warnings for obsolete use of AC_OUTPUT_COMMANDS.

2000-02-10  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_VERBOSE): This is a tab, not spaces.

2000-02-10  Akim Demaille  <akim@epita.fr>

        Changequote busters II.
        They're back to save the world.

        AC_PROG_MAKE_SET, AC_TYPE_GETGROUPS, AC_FUNC_GETLOADAVG,
        AC_FUNC_MKTIME, AC_STRUCT_TIMEZONE, AC_F77_LIBRARY_LDFLAGS): Blast
        that jelly o' changequote.  Set the quotes free.

2000-02-10  Akim Demaille  <akim@epita.fr>

        Interrupting autoheader left temp files.
        From Jim Meyering.

        * autoheader.sh (usage): The usage is to use $0 here.
        (ah_base): Be in TMPDIR.
        Install the `trap' before creating the first tmp file.
        Also trap on 0.

2000-02-10  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_OUTPUT_MAKE_DEFS): This is a routine of
        `configure', not `config.status', hence use `conftest' for tmp
        files, not `$ac_cs_root'.
        Removed forgotten developer comment.
        Double quoting the whole body is nicer than just the part that
        needs to be.

2000-02-10  Akim Demaille  <akim@epita.fr>

        * tests/torture.m4: Also check the value of @DEFS@ when no
        CONFIG_HEADER is used.

2000-02-10  Akim Demaille  <akim@epita.fr>

        Changequote-busters!
        From Dan Ackroyd.

        * acgeneral.m4 (AC_INIT_PARSE_ARGS, AC_INIT_PREPARE,
        AC_CACHE_SAVE, AC_PREFIX_PROGRAM, AC_OUTPUT,
        _AC_OUTPUT_CONFIG_STATUS, AC_OUTPUT_MAKE_DEFS, AC_OUTPUT_FILES,
        _AC_OUTPUT_HEADERS, AC_OUTPUT_LINKS, AC_OUTPUT_SUBDIRS): Quit
        playing with changequotes, @BKL@ and Co.!  Just quote properly.

2000-02-10  Akim Demaille  <akim@epita.fr>

        Honor properly the `#define' config.h.in templates.
        Test it.

        * acgeneral.m4 (AC_OUTPUT_HEADERS): Rename as...
        (_AC_OUTPUT_HEADERS): this.  All callers changed.
        Don't mess with changequote, just quote properly.
        Bug 1.  Because of the `#' in `ac_dA', the quotes <<>> were not
        removed, and therefore the sed script contained `<<define>>'
        instead of `define'.  Now that the block is properly quoted, there
        is no need to quote `define'.
        Bug 2.  Once a `#define' substitution performed, we were branching
        to the top of the sed script (`t top').  This resulted in an
        endless substitution of `#define foo 1' to `#define foo 1'.
        Branching is not enough: you also have to fetch the next input
        line, i.e., use `t' instead of `t t' in ac_dD, and don't output
        `: top' in `config.defines'.
        Though it was correct for `#undef' templates, just apply the same
        transformation to `ac_uD' and `config.undefs'.
        Bug 3.  Don't try to preserve what was behind the value in the
        template, since on
                #define NAME "bar baz"
        it leads to
                #define NAME 1 baz"
        Now `ac_dB' catches everything behind the NAME (making sure there
        is at least a space) and `ac_dC' only outputs a space.
        * tests/torture.m4: Check that various forms of `#define' header
        templates are properly handled.

2000-02-10  Akim Demaille  <akim@epita.fr>

        Avoid calling `rm' without arguments.

        * acgeneral.m4 (_AC_OUTPUT_CONFIG_STATUS): It is smarter to use a
        quoted here doc to output the section providing defaults for
        CONFIG_*.
        Don't rm the CONFIG_FILES here but in..
        (AC_OUTPUT_FILES) [test -n "$CONFIG_FILES"]: here.
        Hm, actually, no, just don't remove them at all, let the newly
        created files replace the old ones, exactly as in
        AC_OUTPUT_HEADERS.
        From Graham Jenkins.

2000-02-10  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (_AC_OUTPUT_CONFIG_STATUS): Don't
          : ${FOO="$foo"}
        but
          : ${FOO=$foo}
        Since Ultrix will also assign the quotes to FOO.
        Reported by Harlan Stenn.

2000-02-10  Akim Demaille  <akim@epita.fr>

        Keep `AC_CHECK_TYPE' backward compatibility and provide a proper

2000-02-10  Akim Demaille  <akim@epita.fr>

        * libm4.m4 (near m4_split): Remove the buggy additional
        changequote.
        Quote properly `m4_split' when registering it.

2000-02-10  Akim Demaille  <akim@epita.fr>

        The AU-glue code for AC_LINK_FILES was not fully compatible: in
          AC_LINK_FILES($from, $to)
        `$from' and `$to' can be lists, hence `AC_CONFIG_LINKS($to:$from)'
        is wrong.
        Reported by H.J. Lu.

        * acgeneral.m4 (AC_LINK_FILES): Replace the m4-glue code from
        AC_LINK_FILES to AC_CONFIG_LINKS, with sh-glue code.
        Give a detailed update message.
        (_AC_LINK_FILES_CNT): New variable.  Initialize.

        * acspecific.m4 (AC_PROG_SED): Removed.

2000-02-10  Akim Demaille  <akim@epita.fr>

        AC_CHECK_FILES has never worked properly.

        * acgeneral.m4 (AC_CHECK_FILE): Use AC_CACHE_CHECK.
        * autoheader.m4 (AC_CHECK_FILES): AH-define.
        * tests/semantics.m4: Test AC_CHECK_FILES.
        * tests/atspecific.m4 (TEST_MACRO): Don't.

2000-02-10  Akim Demaille  <akim@epita.fr>

        No longer use a diversion to store the sed program implementing
        AC_SUBST.

        * acgeneral.m4 (_AC_SUBST): New macro.
        (_AC_SUBST_SED_PROGRAM): Initialize.
        (AC_SUBST): Use _AC_SUBST.
        (AC_SUBST_FILE): Likewise.
        (AC_DIVERSION_SED): Removed.  Renumber the AC_DIVERSIONs.
        (AC_OUTPUT_FILES): Instead on undiverting AC_DIVERSION_SED, output
        _AC_SUBST_SED_PROGRAM.

2000-02-10  Akim Demaille  <akim@epita.fr>

        Standardize the error messages in the options handling of

        Change the error messages from
          value: invalid feature name
        to
          invalid feature: value
        Invite the user to try --help for invalid options.
        (AC_INIT_PARSE_ARGS): Likewise.

2000-02-10  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_OUTPUT_COMMANDS_COMMANDS): Rename as...
        (_AC_OUTPUT_COMMANDS): This.  All callers changed.
        Disable the verbose message until Automake uses the new features
        of `config.status'.
        Reported by Jim Meyering.

2000-02-10  Akim Demaille  <akim@epita.fr>

        Clean up a few changequotes.

        Fix the handling of `./configure foo=bar' and test it.

        * acgeneral.m4 (AC_INIT_PARSE_ARGS, getopt loop): Always define
        ac_optarg as the rhs of the first `=', not only on `-.*=', so that
        `configure var=val' defines ac_optarg=val.
        Improve the robustness to shell special characters:
         - Use grep when checking that shell variable names are valid.
         - Quote the quotes in ac_optarg before `eval var='$ac_optarg''.
         - Quote the quotes when building ac_configure_args.

        * tests/torture.m4: Test that `./configure foo=bar' works properly.

2000-02-09  Akim Demaille  <akim@epita.fr>

        Resynchronize `INSTALL' with the current `configure', and
        conversely...

        * acgeneral.m4 (AC_INIT_PARSE_ARGS): Let `configure' support `-h =
        --help' and `-n = --no-create'.
        Document -h, -n and -q in configure's help message.

2000-02-09  Akim Demaille  <akim@epita.fr>

        Clean up `make clean'.

        * Makefile.am (CLEANFILES): Added autoupdate.m4f and autoconf.tmp.
        * tests/torture.m4: Rm dummy and dummy.in.

2000-02-09  Akim Demaille  <akim@epita.fr>

        Test `autoupdate'.

        * tests/tools.m4 (AH_DEFUN): Fix the comments.
        Quote properly.
        (autoupdate): New test.

2000-02-09  Akim Demaille  <akim@epita.fr>

        AU_ glue code for AC_OUTPUT with arguments.

        * acgeneral.m4 (AU_DEFINE): New macros, pulled out from AU_DEFUN.
        Defines a macro in `autoupdate::' with all the required wrapping
        for `autoupdate'.
        (AU_DEFUN): Use it.
        (AC_OUTPUT): When dispatching your arguments, use ifval, not
        ifset!
        Dispatch actions to AC_CONFIG_COMMANDS not AC_OUTPUT_COMMANDS, to
        avoid unneeded warnings for obsolete use of AC_OUTPUT_COMMANDS.
        (autoupdate::AC_OUTPUT): New macro.
        * doc/autoconf.texi (Writing configure.in, the example): Don't
        advocate AC_OUTPUT with args.
        (Output, AC_OUTPUT with args): Simplify the documentation, and
        provide the translation into the new scheme.
        Propagate what remained into the proper sections.

2000-02-09  Akim Demaille  <akim@epita.fr>

        AU_ glue code for AC_OUTPUT_COMMANDS.

        * acgeneral.m4 (AC_OUTPUT_COMMANDS): AU_DEFUNed in terms of
        AC_CONFIG_COMMANDS.
        (AC_OUTPUT_COMMANDS_CNT): New variable, declared both in
        `autoconf::' and `autoupdate::'.
        (AC_OUTPUT): Register your arguments to AC_OUTPUT_COMMANDS only if
        there are to avoid spurious `run autoupdate' messages.
        * doc/autoconf.texi (Libraries): Document the changes.

2000-02-09  Akim Demaille  <akim@epita.fr>

        Avoid outputting `config_files' code in `config.status' if there
        are none.

        * acgeneral.m4 (AC_OUTPUT): Don't register $1 to `AC_CONFIG_FILES'
        if $1 is empty.

        * Makefile.am: Tuned.

2000-02-09  Akim Demaille  <akim@epita.fr>

        Extend the concept of `INIT-CMDS' to the AC_CONFIG_FOOS.

        * acgeneral.m4 (_AC_CONFIG_COMMANDS_INIT): New macro which will
        collect the `INIT-CMDS'.
        (AC_CONFIG_COMMANDS, AC_CONFIG_LINKS, AC_CONFIG_HEADERS,
        AC_CONFIG_FILES): Use it, and also temporarily divert to -1
        instead of spamming dnl everywhere.
        (AC_OUTPUT_CONFIG_STATUS): Make sure to output the INIT-CMDS
        before the other sections, it'd be a pity to initialize after the
        use :).

        * doc/autoconf.texi (Configuration Actions): New section,
        documenting the common behavior of AC_CONFIG_FILES,
        AC_CONFIG_HEADERS, macro AC_CONFIG_COMMANDS, and AC_CONFIG_LINKS.
        (Configuration Files): Document $2 and $3 of AC_CONFIG_FILES.
        (Configuration Headers): Document $2 and $3 of AC_CONFIG_HEADERS.

        (_AC_VERSION_COMPARE): New macro.
        (AC_PREREQ): Use it.

2000-02-09  Akim Demaille  <akim@epita.fr>

        * tests/base.m4: Really added to the CVS repository.
        * tests/tools.m4: Likewise.

2000-02-09  Akim Demaille  <akim@epita.fr>

        * tests/base.m4: s/m4 -I ../m4 -I $at_top_srcdir/.

2000-02-08  Akim Demaille  <akim@epita.fr>

        * autoheader.sh (debug): Initialize to `false', not 0.

2000-02-08  Akim Demaille  <akim@epita.fr>

        Fix a bug: `libm4::define' was incorrectly registered.

        * libm4.m4 (libm4::define): Not only register, define too.

2000-02-08  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_COMPILE_CHECK): Use AU_DEFUN, remove the call
        to AC_OBSOLETE.

2000-02-08  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_PROVIDE): Use `m4_define', not `define'.
        Because of the names pace machinery this change makes `autoconf'
        about four times faster on complex `configure.in's.

2000-02-08  Akim Demaille  <akim@epita.fr>

        Open the access to AH_ to users.

        * autoheader.m4 (autoheader::AH_DEFUN): New macro.
        * tests/tools.m4: New file, in charge of testing the scripts.
        All the dependencies adapted.
        * tests/actest.m4 (autoheader::AC_TATOOINE): New macro, used while
        testing autoheader.
        * tests/atspecific.m4: Create config.hin instead of config.h.in.

2000-02-08  Akim Demaille  <akim@epita.fr>

        Because of commas and brackets, m4_split must mess with the
        quotes.

        * libm4.m4 (m4_split): Quote the elements of the list you produce.
        * tests/base.m4: New file, testing libm4.
        All callers adapted.
        Test m4_wrap.

2000-02-08  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_CONFIG_UNIQUE): Strip the `:foo.in' part
        yourself, in order to give better error messages.
        (AC_CONFIG_IF_MEMBER): Adapted to the above change.
        Quote some regexp active characters ([+.*]).
        Suggested by Alexandre Oliva.

2000-02-08  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_INCLUDES_DEFAULT): Make it more robust to
        the fact it is used non quoted.
        Reported by Jim Meyering.

2000-02-08  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_OUTPUT_FILES): Simplify some excess in
        changequote.
        (AC_OUTPUT_SUBDIRS): Likewise.

2000-02-08  Akim Demaille  <akim@epita.fr>

        * autoupdate.sh: Don't dump --help on --wrong-option.
        * autoconf.sh: Reformatting, and use >&2 instead of 1>&2.
        * autoreconf.sh: Likewise.
        * autoheader.sh: Likewise.

2000-02-08  Akim Demaille  <akim@epita.fr>

        * libm4.m4 (m4_namespace_push, m4_namespace_pop): Use the private
        macros to be robust to name space changes.
        (m4_popdef, m4_pushdef): New private macros.

2000-02-08  Akim Demaille  <akim@epita.fr>

        Let the doc catch up.

        * doc/autoconf.texi (Common Behavior): New section, to document
        the common behavior of the macros.
        (Standard Symbols): New subsection.  Describes the transformation
        of the AC_DEFINEd names.
        (Default Includes): New subsection.  Obvious content.
        All the ``callers'' updated.

2000-02-08  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_OUTPUT_HEADERS): Don't use `break' to exit the
        while loops which are breaking conftest.defines and
        conftest.undefs into smaller snippets: just use the proper
        condition for the while.
        Suggested by Alexandre Oliva.

2000-02-08  Akim Demaille  <akim@epita.fr>

        * doc/autoconf.texi (Configuration Commands): New section, for
        AC_CONFIG_COMMANDS.
        Move the definition of AC_OUTPUT_COMMANDS here.
        (Configuration Links): New section, for AC_CONFIG_LINKS and
        AC_LINK_FILES.
        (Configuration Files): New section, for AC_CONFIG_FILES.
        (Globally) Promote AC_CONFIG_HEADERS over AC_CONFIG_HEADER.
        (Using System Type): Don't document AC_CONFIG_LINKS and
        AC_LINK_FILES.
        (Invoking config.status): Mention CONFIG_COMMANDS.
        Document --file and --header.
        Talk first of the newest interface of config.status.

2000-02-08  Akim Demaille  <akim@epita.fr>

        Introduce a concept index, and update a bit the documentation.

        * doc/autoconf.texi (Concept Index): New section.
        Various entries added.
        (Typedefs): Rename as...
        (Types): this.  Pay attention to not limiting the documentation to
        the typedefs.
        (Particular Types): Mention the equivalent generic test.
        Promote the GNU coding style at various places.

2000-02-08  Akim Demaille  <akim@epita.fr>

        Revamp the autoupdate/AC_OBSOLETE chain.  All the details are
        given in the prologue of acoldnames.m4.

        * acgeneral.m4 (Prologue): Enter the `autoconf' name space.
        (AU_DEFUN): New macro.

        * autoupdate.m4: New file.
        Disable the name spaces `autoconf', and `libm4'.  Disable libm4.
        * Makefile.am: Tuned to support the changes above.

        * autoupdate.sh: Model after autoconf.sh.
        Can run on several files at once (for instance m4/*.m4).
        Don't touch files that are up to date.
        Run m4 on autoupdate.m4f instead of playing with sed.


        Use AU_DEFUN.

        * acgeneral.m4 (AC_LINK_FILES, AC_ENABLE, AC_WITH): Use AU_DEFUN,
        remove the call to AC_OBSOLETE.
        * acspecific.m4 (AC_CYGWIN32): Likewise.
        * acoldnames.m4: Replaced all the definitions via `define' or
        `AC_DEFUN' to use `AU_DEFUN'.

2000-02-08  Akim Demaille  <akim@epita.fr>

        Clean up some m4 files.

        * acoldnames.m4: Use `#', not `dnl'.
        Don't spread `dnl' everywhere, anyway, we are in a divert(-1).
        * autoconf.m4: Likewise.
        * autoheader.m4: Likewise.

2000-02-08  Akim Demaille  <akim@epita.fr>

        Clean up autoconf.

        * autoconf.sh: Minor reorganizations to clearly separate the
        prologue, which is almost common to all the shell scripts of
        Autoconf, and the body.

2000-02-08  Akim Demaille  <akim@epita.fr>

        Improve support of name spaces in libm4.  Put the m4 builtins
        in the `libm4' name space.

        * libm4 (m4_changequote, m4_define, m4_defn, m4_dnl, m4_indir,
        m4_undefine): Private copies in the global name space.  Used by
        the name space mechanisms.
        (m4_namespace_register): New macro.
        (m4_namespace_define): Use it.
        (builtin, changequote, defn, dnl, esyscmd, ifdef, ifelse, indir,
        patsubst, popdef, pushdef, regexp, undefine, syscmd, sysval): Put
        in the `libm4' name space.
        (m4_disable, m4_enable): Use the private m4_indir, otherwise once
        `libm4' closed, there is no `indir' available, and therefore no
        means to reopen a name space.

2000-02-08  Akim Demaille  <akim@epita.fr>

        Output really nothing if AC_INIT was not given.  Unconditional
        output can be problematic with autoupdate.

        * acgeneral.m4 (AC_INIT_NOTICE): Output ac_includes_default.
        (Default includes section): No longer dump ac_includes_default in
        AC_DIVERSION_INIT.

2000-02-08  Akim Demaille  <akim@epita.fr>

        * libm4.m4 (m4_namespace_define): Fix a bug: `m4_namespace'
        instead of `$1'.
        Simplify some excess in quoting.
        Use NAMESPACE::MACRONAME instead of `m4_defn(NAMESPACE,
        MACRONAME)'.

2000-02-08  Akim Demaille  <akim@epita.fr>

        Adapt autoheader to use libm4's name spaces.

        * autoheader.m4 (AH_HOOK): Removed.
        (AH_DEFUN): Define in the `autoheader' name space.
        Use only AH_DEFUN to define macros in this file.
        (epilogue): No longer run the `AH_HOOKS', enter the `autoheader'
        name space.

2000-02-08  Akim Demaille  <akim@epita.fr>

        Clean up a bit the user interface.

        * autoconf.sh: Give your name while reporting errors.
        Don't spit --help for errors on arguments.
        * autoreconf.sh: Likewise.
        * autoheader.sh: Likewise.
        More temporary files that one can browse when debugging.
        Don't ${var}, just $var.
        Don't dump --help when the arguments are invalid.
        (config_h): Use the empty value instead of `undefined' to check
        that it is defined.
        * acspecific.m4: Formatting changes.

2000-02-08  Akim Demaille  <akim@epita.fr>

        Introduce name spaces in libm4.

        m4_namespace_define, define, m4_disable, m4_enable, m4_rename):
        New macros.
        (_m4_foreach, _m4_for, m4_wrap): Use m4_define for temporaries.
        (m4_split): Don't mess with the quotes.

        * acgeneral.m4 (AC_OUTPUT_MAKE_DEFS, AC_OUTPUT_HEADERS): Quote
        `define'.

2000-02-08  Akim Demaille  <akim@epita.fr>

        * doc/autoconf.texi (Introduction): m4 1.4 is now required.
        (Invoking autoconf): A better help on --trace.
        (Defining Symbols): Advocate a proper use of the quotes in m4
        code, including if the quotes are sometimes useless.  It is bad,
        very bad not to quote properly, so quote all the examples
        properly.
        (Cache Files): Use a unary call to define, instead of an empty
        $2.
        (Using System Type): Watch out TeX wrapping.
        (Pretty Help Strings): Don't give too long a snippet of --help.
        Promote the coding style of Autoconf.  Quote properly.

2000-02-08  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_PRO): Use AC_PROVIDE instead of defining
        yourself.  This allows to see everything that is AC_PROVIDEd via
        autoconf --trace.
        (AC_SPECIALIZE): define'd, not AC_DEFUN'd.
        (AC_PROVIDE): Use define with a single arg, instead of an empty $2.

2000-02-08  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (ac_includes_default): Don't use simple quotes, but
        doubles quotes if you want to use \-continuation lines: this is
        not recognized by MIPS' sh.

2000-02-08  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4. Formatting changes.
        * acspecific.m4: Likewise.

2000-02-08  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_CONFIG_HEADERS, AC_CONFIG_LINKS,
        AC_CONFIG_SUBDIRS): A space was missing to separate the arguments
        of m4_append.

2000-02-08  Akim Demaille  <akim@epita.fr>

        Arrange that config.status creates the file with the AC_SUBSTing
        engine only if needed.

        * acgeneral.m4 (AC_OUTPUT_FILES): Create the sed code only if test
        -n "$CONFIG_FILES".

2000-02-08  Akim Demaille  <akim@epita.fr>

        Promote AC_LANG_CASE.

        * acgeneral.m4 (AC_TRY_COMPILER, AC_TRY_LINK_FUNC, AC_CHECK_LIB,
        AC_TRY_COMPILE, AC_TRY_LINK, AC_TRY_RUN_NATIVE, AC_CHECK_FUNC):
        Use AC_LANG_CASE instead of ifelse (AC_LANG, ...).
        (AC_TRY_LINK_FUNC): Quote the body the the AC_DEFUN (whoa, how
        could this survive so long?!?).

2000-02-08  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4: Formatting changes.
        * acspecific.m4: Likewise.

2000-02-08  Akim Demaille  <akim@epita.fr>

        Use the style we promote.

        * doc/autoconf.texi (Header Templates): Promote #if over #ifdef;
        and #undef over #define in templates.
        * acspecific.m4 (AC_DECL_SYS_SIGLIST, AC_FUNC_MMAP,
        AC_FUNC_SETPGRP, AC_FUNC_VFORK, AC_FUNC_SELECT_ARGTYPES): Use #if,
        not #ifdef and #ifndef, indent CPP directives.

2000-02-08  Akim Demaille  <akim@epita.fr>

        Quote properly AC_SHELL_IFELSE and callers.

        * acgeneral.m4 (AC_SHELL_IFELSE): Don't overquote $1.
        (AC_VAR_IF_SET, AC_CHECK_MEMBER, AC_CHECK_LIB, AC_CHECK_HEADER,
        AC_CHECK_DECL, AC_CHECK_FUNC, AC_CHECK_TYPE_INTERNAL): Quote the
        first argument of AC_SHELL_IFELSE.

2000-02-08  Akim Demaille  <akim@epita.fr>

        It seems quite delicate to have AC_INCLUDES_DEFAULT insert the
        default headers in the INIT section of configure: the reason is
        that AC_INCLUDES_DEFAULT is called unquoted, and this results in
        an un expected behavior.  Thanks to Roman V. Shaposhnick for the
        details.

        The current implementation is not satisfying: the default headers
        are defined in the INIT section even if they are not used.

        * acgeneral.m4 (Prologue of AC_INCLUDES_DEFAULTS): Dump the
        definition of ac_includes_default in the INIT section of
        configure.
        (AC_INCLUDES_DEFAULTS): Use it.

2000-02-08  Akim Demaille  <akim@epita.fr>

        * TODO: Updated.
        * THANKS: Updated.

2000-02-08  Akim Demaille  <akim@epita.fr>

2000-02-07  Akim Demaille  <akim@epita.fr>

        Stay in Autoconf's name space.

        * acspecific.m4 (AC_F77_LIBRARY_LDFLAGS): Prefixed with 'ac_':
        arg, save_arg, i, seen, previous_arg, ld_run_path.
        Rename f77_link_output as ac_link_output.
        * tests/actest.m4 (AC_ENV_SAVE): Don't note F77, FFLAGS, FLIBS,
        G77, f77_case, f77_underscore.

2000-02-07  Akim Demaille  <akim@epita.fr>

        Use `#' for comments instead of `dnl'.
        Better highlighting of the sections in the sources.

        * acgeneral.m4: Formatting changes.
        * acspecific.m4: Likewise.
        * autoheader.m4: Likewise.

2000-02-07  Akim Demaille  <akim@epita.fr>

        Create libm4.m4.

        * Makefile.am: Adjusted for libm4.m4.

        * acgeneral.m4 (m4_errprint, m4_warn, m4_fatal, m4_prefix,
        m4_eval, m4_shift, m4_format, m4_include_unique, m4_include,
        m4_sinclude, m4_quote, m4_split, m4_join, m4_strip, m4_append,
        m4_list_append, ifval, ifset, m4_default, m4_case, m4_match,
        m4_foreach): Moved from here, to...
        * libm4.m4: here.
        * acgeneral.m4 (AC_WRAP): Moved from here, to...
        * libm4.m4 (m4_wrap): here.  All callers changed.

        * acgeneral.m4: Don't include acversion.m4.
        * autoconf.m4: Include libm4.m4 and acversion.m4.
        * autoheader.m4: Likewise.

2000-02-07  Akim Demaille  <akim@epita.fr>

        AC_CHECK_SIZEOF: Fix a bug, use standard default headers, and
        test.

        * acgeneral.m4 (AC_CHECK_SIZEOF): Don't over quote $1, some []
        were left in the C code, and had the macro fail.
        Use AC_INCLUDES_DEFAULT.
        * doc/autoconf.texi: Mention default includes.  Explain stdio.h
        must always be given.

        * tests/atspecific.m4 (TEST_MACRO): Updated the list of
        exceptions.
        (AT_CHECK_DEFINES): New macro, to check the content of config.h.
        * tests/semantics.m4: All the tests are updated to use
        AT_CHECK_DEFINES.
        Test AC_CHECK_SIZEOF, AC_CHECK_HEADERS, and AC_CHECK_FUNCS.

2000-02-07  Akim Demaille  <akim@epita.fr>

        Give explicit diagnostics when an input file (for config headers;
        config files etc.) does not exist.
        From Jim Meyering.

        * acgeneral.m4 (AC_OUTPUT_FILES, AC_OUTPUT_HEADERS): Check for the
        existence of source files.

2000-02-07  Akim Demaille  <akim@epita.fr>

        Torture test config.status, AC_SUBST and AC_DEFINE.

        * tests/torture.m4: New file.
        * tests/suite.m4: Include it.

2000-02-07  Akim Demaille  <akim@epita.fr>

        * tests/atspecific.m4 (m4_for, m4_foreach): New macros.

2000-02-07  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_CHECK_TYPE_INTERNAL): Instead of defining an
        unused pointer to the type $1, use
        if (($1 *) 0) return 0;
        to avoid warnings from the compiler.
        From Paul Eggert.

2000-02-07  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_INCLUDES_DEFAULT): Include sys/types.h
        Reported by Jim Meyering.

2000-02-07  Akim Demaille  <akim@epita.fr>

        * tests/atspecific.m4: New file, for AT macros specific to
        Autoconf testing.
        * tests/suite.m4 (AT_TEST_MACRO): Moved to
        * tests/atspecific.m4 (AT_TEST_MACRO): here.
        * tests/syntax.m4 (TEST_MACRO): Moved to
        * tests/atspecific.m4 (TEST_MACRO): here.  Don't test /^AC_INIT/,
        nor /^AC_PROG_\(CC\|CXX\|F77\)_\(GNU\|WORKS\)$/: they are already
        tried elsewhere.
        * tests/Makefile.am: Adjusted.

2000-02-07  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (m4_case): Fixed a typo and a bug: one shift was
        missing.
        (m4_match): New macro.
        * tests/atgeneral.m4 (AT_CASE): Fixed.

2000-02-07  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4: Formatting changes.
        * acspecific.m4: Likewise.

2000-02-07  Akim Demaille  <akim@epita.fr>

        * acspecific.m4 (AC_F77_LIBRARY_LDFLAGS): Don't use FFLAGS_SAVE
        but ac_save_FFLAGS.
        (AC_F77_NAME_MANGLING): Don't use foo_bar but ac_foo_bar.

2000-02-07  Akim Demaille  <akim@epita.fr>

        * acspecific.m4 (AC_C_INLINE): Proceed as for AC_C_CONST:
        condition out the test case if __cpluscplus.
        Don't document the autoheader template twice, one is enough.
        * autoheader.m4 (AC_CONFIG_HEADER): don't hook on this guy, but
        on...
        (AC_CONFIG_HEADERS), since the former is defined on the latter.

2000-02-07  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_CHECK_TYPE_INTERNAL): Use the scheme proposed
        by Alexandre Oliva for testing the definition of TYPE:
        TYPE *foo;
        sizeof (TYPE);

2000-02-07  Akim Demaille  <akim@epita.fr>

        * acspecific.m4 (AC_C_CONST): Don't changequote, there is no need
        for it.  Just quote properly!
        condition out the test case if __cpluscplus.
        AC_REQUIRE AC_PROG_CC_STDC.
        Fix slightly the display of the result (formerly the first run
        says `none needed', and later, because of the cache `no').
        (AC_C_INLINE, AC_C_VOLATILE): AC_REQUIRE AC_PROG_CC_STDC.
        * doc/autoconf.texi (AC_C_CONST): Give a few hints on the
        motivation for trusting the C++ compilers.

2000-02-07  Akim Demaille  <akim@epita.fr>

        * tests/atgeneral.m4: Updated.
        (AT_CASE): new macro.
        (AT_CHECK): Use it.  Don't changequote for patsubst, there is no
        need.
        * tests/syntax.m4 (TEST_MACRO): Don't run AC_ARG_VAR.
        Reported by Jim Meyering.
        Use AT_CASE.

2000-02-07  Akim Demaille  <akim@epita.fr>

        Test that the macros respect the user variable name space.

        * acgeneral.m4 (AC_CANONICAL_THING): define, not AC_DEFUN.
        Don't AC_PROVIDE, there is no need.
        When calling `config.sub`, also || exit 1, to catch failures from
        config.sub.
        * acspecific.m4 (AC_SYS_LONG_FILE_NAMES): Use ac_val, not val.
        (AC_EXEEXT): Use ac_file, not file.
        * tests/actest.m4: New file, holding extra Autoconf macros used
        during the testing.
        (AC_ENV_SAVE): New macro, save the sh variables in a file.
        * tests/suite.m4 (AT_TEST_MACRO, Generation of configure.in):
        include actest.m4, and call twice AC_ENV_SAVE to compare the
        variables before and after the macro.
        * tests/Makefile.am (macro.m4): Don't test macros that are
        required: they will be tested somewhere else.

2000-02-07  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4(AC_CONFIG_PRE_COMMANDS, AC_CONFIG_POST_COMMANDS):
        Rename as AC_CONFIG_COMMANDS_PRE, AC_CONFIG_COMMANDS_POST.  All
        dependencies changed.
        From Jim Meyering.

2000-02-07  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4: Formatting changes.
        * acspecific.m4: Likewise.

2000-02-07  Akim Demaille  <akim@epita.fr>

        Start a new series of tests which check the semantics.

        * acgeneral.m4 (AC_CHECK_MEMBER): It is not smart to define
        ac_Foo, and use AC_Foo.  Got rid of AC_Member_Aggregate and
        AC_Member_Member which were complicating more than simplifying.
        (AC_CHECK_DECLS): Use m4 lists.
        (AC_CHECK_TYPES): A comma was missing.
        * autoheader.m4: (AC_CHECK_DECLS): Use m4 lists.
        * doc/autoconf.texi (Generic Declarations): AC_CHECK_DELCS uses m4
        lists.
        * tests/semantics.m4: New file.  Collection of semantical tests:
        verify that the tests are positive and negative when appropriate.
        Test AC_CHECK_MEMBERS, AC_CHECK_DECLS and AC_CHECK_TYPES.

2000-02-04  Akim Demaille  <akim@epita.fr>

        * tests/Makefile.am (macros.m4): Fix the sed snippet.

2000-02-04  Akim Demaille  <akim@epita.fr>

        * testsuite/autoconf.g/init.exp: Removed, test performed by
        tests/syntax.m4.
        * testsuite/autoconf.g/sizeof.exp: Likewise.
        * testsuite/autoconf.s/defines.exp: Likewise.
        * configure.in (AC_OUTPUT): Adjusted.
        * Makefile.am (SUBDIRS): Adjusted.

2000-02-04  Akim Demaille  <akim@epita.fr>

        * tests/syntax.m4: Test AC_CHECK_SIZEOF.
        * tests/Makefile.am (CLEANFILES, DISTCLEANFILES): Adjusted.
        (macros.m4): Use tmp dest files ($@-t), not directly `$@'.

2000-02-04  Akim Demaille  <akim@epita.fr>

        Hide AH_HOOK behind AH_DEFUN.

        * autoheader.m4 (AH_DEFUN): New macro.  Combination of define and
        AH_HOOK.
        (AC_TRY_RUN, AC_DEFINE, AC_DEFINE_UNQUOTED, AC_CHECK_LIB,
        AC_CHECK_HEADERS, AC_CHECK_HEADERS_DIRENT, AC_CHECK_DECLS,
        AC_CHECK_FUNCS, AC_CHECK_SIZEOF, AC_PROG_LEX, AC_CHECK_MEMBERS,
        AC_CHECK_TYPE, AC_FUNC_ALLOCA, AC_CHECK_TYPES, AC_C_CHAR_UNSIGNED,
        AC_AIX, AC_F77_WRAPPERS, AC_CONFIG_HEADER): All the former calls
        to define and AH_HOOK in autoheader.m4 are replaced by AH_DEFUN.

2000-02-04  Akim Demaille  <akim@epita.fr>

        * acspecific.m4 (AC_RSH, AC_ARG_ARRAY, AC_HAVE_POUNDBANG): No use
        to hide, you are DEFUNCT.

1999-11-14  Akim Demaille  <akim@epita.fr>

        * autoconf.texi (Invoking ifnames): ifnames no longer supports
        --macrodir.

1999-11-13  Akim Demaille  <akim@epita.fr>

        Run the `syntax' test on acgeneral macros too.
        Fix the bugs discovered.

        * acgeneral.m4 (AC_CANONICAL_THING): Quote the
        AC_REQUIRE([AC_CANONICAL_HOST]).  Bug triggered by the use of
        AC_CANONICAL_BUILD alone in configure.in.  Also, quote the
        arguments of macros (eg, ifelse([$1]...), not ifelse($1...)).
        (m4_case): New macro.
        (AC_LINKER_OPTION): Don't clash with user's name space
        (s/i/ac_link_opt).
        (AC_LIST_MEMBER_OF).  You mean AC_FATAL, not AC_MSG_ERROR.
        Quote properly the argument.
        dnl out the empty lines that result from m4 pure code.
        Don't pollute the user name space.
        Use AC_SHELL_IFELSE.
        (AC_F77_NAME_MANGLING): Don't use `test -o'.  There are still
        name space problems.
        * tests/Makefile.am (macros.m4): Also fetch the macros from
        acgeneral.m4.

1999-11-13  Akim Demaille  <akim@epita.fr>

        Really install this patch.

        * acgeneral.m4 (AC_MSG_ERROR, AC_MSG_ERROR_UNQUOTED): Allow an
        optional $2: exit status.

1999-11-13  Akim Demaille  <akim@epita.fr>

        Check that the AC_DEFINEs from acspecific.m4 do have a template.
        Fix the discovered bugs.

        * tests/atgeneral.m4 (AT_CHECK): Don't just exit 1 when you want
        to propagate the failure of a test: exit with the same exit
        status, at least to preserve 77 (=ignore).
        * tests/syntax.m4 (TEST_MACRO): Run also autoheader.  Don't run
        this test on all the macros, some just cannot run without
        arguments.
        * acgeneral.m4 (AC_OUTPUT_CONFIG_STATUS): In the if egrep/fi for
        #define templates, add a `:' to prevent syntax errors in
        config.status when there are no AC_DEFINE performed.
        * autoheader.m4 (AH_TEMPLATE): Don't use _AC_SH_QUOTE here, use it
        in...
        (AH_VERBATIM): here.  Now AH_C_UNSIGNED_CHAR is no longer failing
        (formerly it would produce a non backslashed backquote, which
        made sh choke).

1999-11-13  Akim Demaille  <akim@epita.fr>

        Introduce a means to distinguish failures of `configure' due to
        extern software (so that the test suite doesn't fail on them).

        * acgeneral.m4 (AC_MSG_ERROR, AC_MSG_ERROR_UNQUOTED): Allow an
        optional $2: exit status.
        * doc/autoconf.texi: Document.
        * acspecific.m4 (AC_PROG_CC_WORKS, PROG_CXX_WORKS,
        AC_PROG_F77_WORKS): Exit 77 if the compiler does not work.

1999-11-13  Akim Demaille  <akim@epita.fr>

        Clean up a bit the handling of the LANG stack.  More is needed.

        * acgeneral.m4 (AC_LANG_CASE): New macro.
        (AC_LANG_RESTORE): Use m4_case.
        (AC_LINKER_OPTION): Use AC_LANG_CASE.

1999-11-11  Akim Demaille  <akim@epita.fr>

        * autoconf.texi (Generic Declarations): Fixed a typo which
        prevented `make distcheck' from succeeding.
        * texinfo.tex: Updated for the same reasons.

1999-11-11  Akim Demaille  <akim@epita.fr>

        Introduce a new style of testing, independent from DejaGNU.


        Introduce the logistics.

        * configure.in: Initialize AT, and output tests/atconfig, and
        tests/Makefile.
        * m4/atconfig.m4: New file.
        * m4/Makefile.am: Adjusted.
        * aclocal.m4: Include atconfig.m4.
        * Makefile.am: Adjusted.
        * tests/Makefile.am: New file.
        * tests/atgeneral.m4: Likewise.
        * tests/atconfig.in: Likewise.


        Write tests.

        * tests/syntax.m4: New file, in charge of checking the validity of
        the sh code produced by the macros defined in acspecific.m4.
        acgeneral.m4 is not checked here, because these macros require
        arguments.
        * tests/suite.m4: New file.  Run syntax.m4.

1999-11-10  Akim Demaille  <akim@epita.fr>

        A test suite will be introduced which tries to run all the
        specific macros, but hasbeen'd macro make configure die with bad
        exit status.  So we wish to distinguish live macros from defunct
        macros at the moment they are AC_DEFUN'd, not in their body.  Hm,
        defunct, defunct... Hey!  That's a good name!

        * acgeneral.m4 (AC_DEFUNCT): New macro, comparable to AC_DEFUN,
        but for macros which are no longer defined.  Replaces AC_HASBEEN.
        (AC_HASBEEN): Defunct.  Well, removed in fact.
        (AC_HAVE_LIBRARY): Don't use AC_DEFUN and AC_HASBEEN, just
        AC_DEFUNCT.
        * acspecific.m4 (AC_UNISTD_H, AC_USG, AC_MEMORY_H, AC_DIR_HEADER,
        AC_INT_16_BITS, AC_LONG_64_BITS): Likewise.
        (AC_XENIX_DIR): It was defunct even before I declared it was: was
        depending upon AC_DIR_HEADER which is defunct.  So AC_DEFUNCT'ed
        now.
        (AC_DYNIX_SEQ, AC_IRIX_SUN, AC_SCO_INTL): While we're here, you
        too are defunct now.
        * autoconf.texi (Obsolete Macros): Replace the documentation of
        AC_HASBEEN with that of AC_DEFUNCT.

1999-11-10  Akim Demaille  <akim@epita.fr>

        * autoconf.sh: Formatting changes.
        Removed development junk.
        * acspecific.m4: Formatting changes.
        * autoconf.m4: Likewise.
        * autoheader.m4: Likewise.

1999-11-10  Akim Demaille  <akim@epita.fr>

        Let Autoconf use autoconf's `--install'.

        * m4/Makefile.am: New file.
        * m4/init.am: New file, required by Automake.
        * m4/missing.am: Likewise.
        * m4/sanity.am: Likewise.
        * aclocal.m4: Include them.
        * configure.in (AC_OUTPUT): Added m4/Makefile.

1999-11-10  Akim Demaille  <akim@epita.fr>

        Make autoconf support --install.

        * autoconf.sh (task install): New task.  Extract the set of
        auxiliary m4 files a configure.in depends upon.  Install links
        from library files to the local dir so that the packages depends
        only on local extensions.  Check that the user includes exactly
        the files she needs.

1999-11-10  Akim Demaille  <akim@epita.fr>

        Require GNU m4 1.4 (well 1.3 in fact).

        Because we are ready to handle the case where there are no frozen
        files, we *have* to pass a -I, which is dangerous in conjunction
        with the silent including of `aclocal.m4': you may include things
        that were not expected.  Since anyway handling pre 1.3 complicates
        the task, just require an m4 which supports reloading of frozen
        files.

        * acspecific.m4 (AC_PROG_GNU_M4): Check for --reload.
        * autoconf.sh: Likewise
        * autoheader.sh: Likewise.
        * configure.in: Explicitly state the m4 version you want.

1999-11-10  Akim Demaille  <akim@epita.fr>

        No need for foo="`bar`", foo=`bar` is fine.
        Simplify ${foo} and ${1} into $foo and $1.

        * acgeneral.m4 (ac_LF_and_DOT): Remove the double quotes.
        * acspecific.m4 (AC_PROG_CC_C_O, AC_PROG_F77_C_O): Likewise.
        * autoconf.sh: Likewise.
        * autoheader.sh: Likewise.
        * autoreconf.sh: Likewise.
        * autoupdate.sh: Likewise.
        * ifnames.sh: Remove all the code and messages related to
        AC_MACRODIR, since ifnames is not related to macros in anyway.

1999-11-10  Akim Demaille  <akim@epita.fr>

        New version of AC_INCLUDE, which does not glob, nor rely upon the
        shell.  Add AC_INCLUDES too.  Help tracking multiple inclusions.

        * acgeneral.m4 (m4_errprint, m4_warn, m4_fatal): New macros,
        variations around errprint.
        (m4_include_unique): New macro which registers what are the files
        already included, and warns if some are included several times.
        (m4_include, m4_sinclude): New macro, using m4_include_unique.
        (AC_INCLUDE): Is now just a wrapper of m4_include.
        (AC_INIT): Use m4_sinclude, not sinclude.
        (_AC_ERRPRINT): Removed, m4_errprint is here!
        (AC_WARNING, AC_FATAL): Wrappers of m4_warn and m4_fatal.

1999-11-01  Akim Demaille  <akim@epita.fr>

        * autoheader.sh: No longer rely on a system acconfig.h.

1999-11-01  Akim Demaille  <akim@epita.fr>

        Be kind to Automake: list the arguments of selected macros
        (for instance AC_SUBST will list each variable which may be
        substitued).

        * autoconf.sh (--trace, --output): New options.
        Implement tracing of macros.
        trap also on 0, so that there is no need to rm here and there.
        * autoconf.texi (Output): Document --trace and --output.

1999-11-01  Akim Demaille  <akim@epita.fr>

        Clean up the macros for testing members of aggregates.

        * acgeneral.m4 (AC_CHECK_MEMBER): FATAL if $1 has no dot in it.
        Use AC_INCLUDE_DEFAULTS.
        (AC_C_STRUCT_MEMBER): Removed.
        * acspecific.m4 (AC_STRUCT_TIMEZONE): Adapted to AC_CHECK_MEMBERS.
        (AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Adapted to
        AC_CHECK_MEMBERS and obsoleted.
        (AC_STRUCT_ST_BLOCKS): Adapted to AC_CHECK_MEMBERS.
        * autoconf.texi (AC_STRUCT_ST_BLKSIZE, HAVE_STRUCT_STAT_ST_RDEV):
        Explain they are obsoleted, and how to migrate.
        (AC_STRUCT_ST_BLOCKS, AC_STRUCT_TIMEZONE): Explain that the
        AC_DEFINE changed (but the former #defines remain defined
        currently).
        (AC_C_STRUCT_MEMBER): Removed, replaced by the definitions of
        AC_CHECK_MEMBER and AC_CHECK_MEMBERS.

1999-11-01  Akim Demaille  <akim@epita.fr>

        Install a uniform set of default includes.

        * acgeneral.m4 (AC_INCLUDES_DEFAULT): New macro.  Expands in its
        argument if non empty, otherwise a default list of includes.
        (AC_CHECK_DECL, AC_CHECK_TYPE_INTERNAL): Use AC_INCLUDES_DEFAULT.
        * autoconf.texi: Adjusted.

1999-11-01  Akim Demaille  <akim@epita.fr>

        * autoheader.m4 (AH_FUNC_ALLOCA, AH_C_CHAR_UNSIGNED, AH_AIX):
        Don't leave `[]dnl' in pseudo #-comment (actually CPP directives).

1999-11-01  Akim Demaille  <akim@epita.fr>

        Fix a bit of the brokenness of AC_CHECK_TYPE.

        * acgeneral.m4 (AC_CHECK_TYPE_INTERNAL): New macro, inspired from
        the former AC_CHECK_TYPE.  This macro is exactly the one that
        ought to be named AC_CHECK_TYPE: it just checks, and executes user
        actions.  In the future, this macro ought to be renamed
        AC_CHECK_TYPE.
        There is a big difference with the former AC_CHECK_TYPE: instead
        of grepping in the headers, it tries to compile a variable
        declaration.  This is both safer, slower, and better, since now we
        can check for compiler types (e.g., unsigned long long).

        * configure.in: Use it.

1999-10-31  Akim Demaille  <akim@epita.fr>

        Provide a means to specify commands to run before config.status is
        created (and, for symmetry, after it is created).

        This is typically needed by Automake so that AC_REPLACEd functions
        go through deansification via

        LIBOBJS=`echo $LIBOBJS | sed 's/\.o /\$U.o /g;s/\.o$/\$U.o/'`

        and/or by Libtool which needs to define LTLIBOBJS and others:

        LTLIBOBJS=`echo $LIBOBJS | sed 's/\.o/\.lo/g'`
        AC_SUBST(LTLIBOBJS)

        * acgeneral.m4 (AC_OUTPUT_PRE_COMMANDS): New growing string.

        AC_OUTPUT_CONFIG_STATUS, and AC_OUTPUT_POST_COMMANDS after.

1999-10-31  Akim Demaille  <akim@epita.fr>

        Remove spurious empty lines appearing in configures.

        * acgeneral.m4 (AC_CONFIG_UNIQUE): Produce no output.  Instead of
        fighting with dnl, divert to KILL upon entry, and pop at exit.

1999-10-31  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_INIT_PARSE_ARGS): Avoid using double quotes
        inside "`...`": some shells parse this incorrectly.

1999-10-31  Akim Demaille  <akim@epita.fr>

        * Makefile.am (pkgdata_DATA, EXTRA_DIST): Removed acconfig.h.
        * testsuite/autoconf.s/defines.exp: Commented out, there is no
        longer an acconfig.h.

1999-10-31  Akim Demaille  <akim@epita.fr>

        Create AC_CONFIG_HEADERS which has the same interface as the other
        AC_CONFIG_*S.

        * acgeneral.m4 (AC_CONFIG_HEADERS): New macro, with the same
        interface as AC_CONFIG_LINKS and AC_CONFIG_FILES.
        (AC_LIST_HEADERS_COMMANDS): New growing string, initialize it.
        (AC_CONFIG_HEADER): Rename as...
        (AC_CONFIG_HEADERS): this, for consistency.
        (AC_CONFIG_HEADER): New macro, which calls AC_OUTPUT_HEADERS.
        (AC_OUTPUT_HEADERS): The square brackets for sed and grep were
        not properly quoted: use @BKL@ and @BKR@.
        (AC_OUTPUT_HEADERS): Run the AC_LIST_HEADERS_COMMANDS.

        * acgeneral.m4 (AC_OUTPUT): Once config.status created, before
        running it, trap to `exit 1' so that config.status is not removed
        if configure is interrupted when config.status is complete.

        * acgeneral.m4 (AC_OUTPUT_CONFIG_STATUS): When recognizing
        arguments, accept only foo, and no longer foo:foo.in etc.

1999-10-31  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4: Formating changes.

1999-10-31  Akim Demaille  <akim@epita.fr>

        config.status: Speed up the creation of config headers (about four
        times faster on Linux).

        The previous scheme had three sed commands for each AC_DEFINE: one
        for #define templates, and two for #undef templates (with or
        without trailing spaces).  Divide this in three sed scripts
        instead: a one liner that removes the trailing spaces, one for
        #defines, and then the last for #undef.

        The real speed up comes from the fact that the #define script
        starts by checkin if the current input line has a #define, and if
        not the script immediately goes to the next line, without running
        the rest of the script as was the case before.  Equally for the
        #undef script.

        Note that this way, users that don't use #define templates don't
        pay too much the overhead, since the sed script `realizes' quickly
        there are no #define lines.  My test case runs in 0.32s with
        #define templates, and 0.24s without.  To improve this common
        case, the whole code for #define templates is conditionalized by a
        proper egrep call.  The result runs is 0.24s, i.e., almost no cost
        at all.

        I made one dangerous change that I carefully evaluated before
        commiting: the sed scripts are cut at 48 lines instead of 12 as
        before.  This produces here docs of about 4Kb.  I checked many
        `configure's and they all have big here documents, much bigger
        than the 12 lines (for instance AC_FUNC_MMAP produces a 150 lines
        long, 3800+ character here document).  So I moved to the well
        known HP UX sed limitations: no more than 100 commands, and there
        are two commands per line now, plus a two command preamble.  The
        speed up is noticeable.

        * acgeneral.m4 (AC_OUTPUT_HEADERS): Remove the ac_e
        family.
        Changed ac_uD and ac_dD to `...;t t', instead of `...g'.
        Instead of creating `conftest.vals' with both ac_e, ac_d,
        and ac_u family, preprocess to strip the trailing spaces, and
        create `conftest.defines' with the ac_d family, and then
        `conftest.undefs' for the ac_e family.
        Break up both `conftest.defines' and `conftest.undefs'.  Insert a
        top label and a global test for `#defines' and `#undef' before.
        Call `conftest.defines' if there are #define in the input.
        Call `conftest.undefs'.

1999-10-31  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4: Prefer `>file' over `> file' etc.
        * acspecific.m4: Likewise.

1999-10-31  Akim Demaille  <akim@epita.fr>

        Rename the family AC_NEED_DECL as AC_CHECK: it is more uniform,
        but keep defining NEED_FOO_DECL when `foo' is not declared.  Files
        not using Autoconf behave better when declarations lacks than when
        they are wrong.  So the unset position should off, hence #if NEEDS
        instead of #if !HAVE (which is triggered when HAVE is not set).

        * acgeneral.m4 (AC_NEED_DECL): Rename as...
        (AC_CHECK_DECL): This.  Make sure the arguments are the usual
        IF-FOUND, IF-NOT-FOUND.
        (AC_NEED_DECLS, AC_CHECK_DECLS): Likewise.
        * autoconf.texi (Generic Declarations): Document the changes
        aforementioned.

        (AH_CHECK_DECLS): This.
        (AH_HOOKS): Hook AH_CHECK_DECLS on AC_CHECK_DECLS instead of
        _NEED_.

1999-10-31  Akim Demaille  <akim@epita.fr>

        Revamp the handling of the arguments of config.status: instead of
        looping over config_files etc. to recognize the file names, use
        the case which handles the options.
        Suggested by Alexandre Oliva.

        * acgeneral.m4 (ifset): Rename as...
        (ifval): This.  All callers changed.
        (ifset): New macro, which tests if a macro is set to a non empty
        value.

        * acgeneral.m4: Initialize growing lists and strings to empty, to
        ease the tests.
        (AC_CONFIG_HEADER): Quote AC_LIST_HEADERS in the define, to handle
        the case AC_LIST_HEADERS is initialized.

        * acgeneral.m4: (AC_OUTPUT_CONFIG_STATUS): New macro, pulled out
        from...
        (AC_OUTPUT): Instead of using $1, $2 and $3, pass them to the
        official macros (AC_CONFIG_FILES, AC_OUTPUT_COMMANDS).
        Call AC_OUTPUT_CONFIG_STATUS.
        (option handling): Use the case-esac to recognize arguments.
        (AC_OUTPUT_COMMANDS): Fix the missing fi;done.

1999-10-31  Akim Demaille  <akim@epita.fr>

        Add a means to specify commands to be run by config.status.  At
        the difference of AC_OUTPUT_COMMANDS, require that the set of
        commands be named, so that both
                CONFIG_COMMANDS=foo ./config.status
        and
                ./config.status foo
        perform the Right Thing.

        * acgeneral.m4 (AC_CONFIG_UNIQUE): Also check in
        AC_LIST_COMMANDS.
        (AC_CONFIG_FILES): Remove a dead pushdef.

        in config.status.
        (AC_OUTPUT): Take AC_LIST_COMMANDS into account.
        (AC_OUTPUT): Call AC_OUTPUT_COMMANDS_COMMANDS.

1999-10-31  Akim Demaille  <akim@epita.fr>

        New macro: AC_CONFIG_FILES which is very much like AC_OUTPUT but
        that one associates commands to run when a config file is created.
        For instance for a shell script `foo', one uses
        AC_CONFIG_FILES(foo, chmod +x foo).

        In addition, check that the same name is never used twice in
        config files, headers, subdirs and links.

        * acgeneral.m4 (m4_append): Don't insert new line between
        elements.

        of a config list.
        (AC_CONFIG_UNIQUE): New macro which ensures that a config file
        name is not yet used.
        (AC_CONFIG_HEADER, AC_CONFIG_LINKS, AC_CONFIG_SUBDIRS): Use
        AC_CONFIG_UNIQUE.

        * acgeneral.m4 (AC_CONFIG_FILES): New macro.
        (AC_LIST_FILES): New list, which stores arguments of
        AC_CONFIG_LISTS the same as AC_LIST_LINKS stores AC_CONFIG_LINKS
        etc.
        (AC_OUTPUT): No longer rely on $1 to designate the config files:
        register them via AC_CONFIG_FILES.  All uses of $1 replaced by
        uses of AC_LIST_FILES.
        (AC_OUTPUT_FILES): Run the commands associated to the
        CONFIG_FILES.

1999-10-31  Akim Demaille  <akim@epita.fr>

        The sed quoting script depends on the shape of the commands used

        Make the handling of the configuration links (AC_LINK_FILES)
        exactly the same as that of configurations files (AC_OUTPUT_FILES)
        and headers (AC_CONFIG_HEADERS).  As a result, it is sane to run
                ./config.status src/libmy_lib
        or
                CONFIG_LINKS=src/lib_mylib:lib/lib_mylib ./config.status

        * acgeneral.m4 (AC_LINK_FILES): Use AC_FATAL to diagnose bad
        number of argument.
        Obsoleted (but implemented) in favor of AC_CONFIG_LINKS.

        * acgeneral.m4 (AC_CONFIG_LINKS): New macro.  Takes space
        separated list of DEST:SOURCES arguments.

        * acgeneral.m4: Rename each occurrence of AC_LIST_HEADER as
        AC_LIST_HEADERS for consistency.

        * acgeneral.m4 (AC_OUTPUT, config.status prologue): Move the
        definition of config_files and config_headers to the top.
        Add the definition of config_links.
        Change the help message to use the aforementioned variables.

        * acgeneral.m4 (AC_OUTPUT_LINKS): Adapted to the new scheme of

        Explicit the obsoleteness of AC_LINK_FILES.

1999-10-01  Akim Demaille  <akim@epita.fr>

        Moving most of the task of creating config.h.in from sh to m4.
        Getting rid of acconfig.h by supply a major new family of macros:
        AH_* which make it possible to insert arbitrary text into
        config.h.in.

        * autoheader.m4: Major rewrite: introduction of a set of macros
        AH_ that produce code into config.h.in.  There are two sets of
        macros: generic macros, or specialized, documented below.  The
        basic idea is that an AC_FOO macro which needs an entry in
        config.h.in should have a sibling AH_FOO which expands into that
        entry.  In a near future, these macros will be moved next to their
        siblings.

        * autoheader.m4 (AH_VERBATIM, AH_DEFINE, AH_DEFINE, AH_NEED_DECLS,
        AH_CHECK_SIZEOF, AH_CHECK_FUNCS, AH_CHECK_HEADERS,
        AH_CHECK_HEADERS, AH_CHECK_LIB, AH_PROG_LEX, AH_FUNC_ALLOCA,
        AH_C_CHAR_UNSIGNED, AH_AIX, AH_F77_WRAPPERS): New macros.

        * autoheader.m4 (End section): Bind AC_ macros to their
        AH_siblings.

        * autoheader.sh: Remove the sections in charge of SYMS, TYPES,
        FUNCS, HEADERS, LIBS and DECLS: autoheader.m4 is now in charge of
        these.

        * autoheader.sh (options): Added -d, --debug, which does not
        remove the temporary files.

        * autoheader.sh: Instead of redirecting stdout to the output
        stream, always output to a temporary file.  This allows to change
        slightly the consistency check: before autoheader would check that
        each non documented AC_DEFINE is templated in an acconfig.  Now it
        just checks whether the template is in the output file.

        * acconfig.h: Completely emptied, the remaining templates
        (_ALL_SOURCE, __CHAR_UNSIGNED__, F77_FUNC, F77_FUNC_,
        HAVE_STRINGIZE, and STACK_DIRECTION) are now either associated to
        their AC_DEFINE, or to one of the new AH_ macros.

        * acgeneral.m4: Reordering of the m4 macros which are not specific
        to Autoconf.

        * acgeneral.m4 (AC_HAVE_LIB): Promoted from obsolete to hasbeen.

        * acgeneral.m4 (AC_TR_CPP): Fixed quoting problem, and missing ^
        in patsubst.
        (AC_TR_SH): Fixed quoting problem.

1999-09-29  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_WRAP): Don't output an extra space after the
        last word.

1999-09-29  Ben Elliston  <bje@cygnus.com>

        * acspecific.m4 (AC_FUNC_GETLOADAVG): Check for the kstat_open()
        function in libkstat (on systems such as Solaris). This family of
        functions is preferred since they don't require setgid permissions
        to use them. Fix for PR autoconf/65.

1999-09-29  Akim Demaille  <akim@epita.fr>

        * acconfig.h: Commit the change announced below.

1999-09-29  Akim Demaille  <akim@epita.fr>

        From Jim Meyering.

1999-09-28  Akim Demaille  <akim@epita.fr>

        Start to get rid of acconfig.h.  It is an anachronism.

        X_DISPLAY_MISSING, YYTEXT_POINTER): Removed their autoheader
        template.  They are now documented with their own AC_DEFINE.

        * acgeneral.m4 (AC_HASBEEN): New macro.  Same as AC_OBSOLETE, but
        dies.

        * acspecific.m4 (AC_UNISTD_H, AC_USG, AC_MEMORY_H, AC_INT_16_BITS,
        AC_LONG_64_BITS): Promoted from obsolete to hasbeen.

        * autoheader.m4 (AC_DEFINE_UNQUOTED): Define via AC_DEFINE, so
        that we program things only once.
        (AC_DEFINE): Use AC_WRAP and _AC_SH_QUOTE.  It is now safe to have
        backquotes and extra spaces in the third argument, without
        yielding a bad result.

        * autoheader.m4: Instead of a huge `eval', use a temporary file.
        (option handling): Added --debug, to keep the temporary files.
        Fixed a couple of missing quotes.

        (AC_INIT_PARSE_ARGS, --help): Output ac_arg_enable_help,
        ac_arg_with_help, and ac_arg_var_help.

        influent envvars.
        * acspecific.m4 (AC_PROG_CC): Document CFLAGS.
        This is mainly to test AC_ARG_VAR.  Var to document are to be

        All callers changed.

        * autoconf.sh (Checking for Bugs): Remove the indirection that
        made the `sort -u' useless.

1999-09-21  Akim Demaille  <akim@epita.fr>

        * autoconf.sh (Last sed cmd): Change also @PND@ to `#', since this
        is also a symbol very hard to quote in m4.

        * acgeneral.m4 (AC_CHECK_LIB): Use AC_VAR_*.

        * acgeneral.m4: Use `m4_BUILTIN' instead of indirection via

        (AC_CHECK_FUNC): Likewise.

        * Makefile.in (${srcdir}/configure): Use autoconf.sh to build
        Autoconf's configure.  Before the building was performed running
        m4 at hand, but much was not done (e.g., __oline__,
        @BKL@... expansion)

1999-09-20  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_OUTPUT): Don't remove the CONFIG_HEADERS
        unconditionaly: it breaks the `config.h has not changed' trick.

1999-09-17  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_INIT_PARSE_ARGS): Improve configure's --help.

        * acgeneral.m4 (AC_OUTPUT): Change the root of filenames of
        config.status from $conftest to $confstat.
        The previous patch to make config.status reentrant was wrong,
        because it changed some `conftest' that are used by configure into
        `$conftest', while it was for config.status only.  To avoid
        another confusion like this, all the filenames of config.status
        should be `$confstat*', and those of configure should be
        `conftest*'.
        (AC_OUTPUT): Rename the uses of `ac_file' for the sed fragments as
        `ac_sed_frag'.

        * acgeneral.m4 (AC_OUTPUT): This macro used to open the here
        documents that configure uses to generate config.status, included
        that of the submacros.  Now, it no longer handles the here
        documents for its subroutines (it was far to hard to track).
        (AC_OUTPUT_FILES): Open and close your here documents to
        $CONFIG_STATUS.
        (AC_OUTPUT_HEADER): Likewise.
        (AC_OUTPUT_LINKS): Likewise.

        * acgeneral.m4 (AC_OUTPUT_FILES): Move $ac_vpsub and $extrasub
        from the AC_SUBST substitutions (i.e., that of @SHELL@ etc.) to
        the specific section (that of @srcdir@ etc.).
        Now the ``general substitution'' section is absolutely uniform.

        * acgeneral.m4 (AC_SUBST): Change sed call from `s%@from@%to%g'
        into `s%@from@%to%;t t'.
        (AC_SUBST_FILE): Likewise.
        (AC_OUTPUT_FILES): Optimize the sed scripts by branching if there
        are no `@' on the line. Impressive speed up.

        Reported by Christian Krone.

        * acgeneral.m4 (AC_INCLUDE): New macro.

        sub-configures.

        * acgeneral.m4 (Configuration): Accept --env-VAR=VALUE and
        VAR=value.
        * autoconf.texi, install.texi: Document it.

1999-09-14  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (AC_HELP_STRING): Rewrite in m4.  Have m4 work, and
        give a break to sh.
        (_AC_FOREACH): Be careful not to evaluate the arguments.  A loop
        over *quoted* macro names should loop over the macro names, not
        upon their expansion.
        (_AC_COMMATIZE): Also swallow end of lines.

        * autoconf.texi (Pretty Help Strings): Updated to reflect the
        changes.

1999-09-13  Akim Demaille  <akim@epita.fr>

        * acgeneral.m4 (ifset): New helpy tiny macro.
        (AC_OUTPUT): Improved --help of config.status.
        (AC_OUTPUT): Remove inconditionaly all the files to be updated.
        (AC_OUTPUT): Use pid to define the temporary file names in order
        to allow parallel builds.

        * autoconf.sh: Substitute also /@BKL@/[/ /@BKR@/]/ /@DLR@/$/ so
        that these characters are more easily accessible from m4 without
        turning changequote juggling into a nightmare.

        * acgeneral.m4 (AC_WRAP): New macro, for word wrapping.

        * autoconf.texi: Update the direntry for more modern Texinfos.
        Add pointer to configure and config.status.
        Remove the dots from the menus: horizontal space is precious.
        (Invoking config.status): More traditional presentation of the options.

1999-09-07  Ben Elliston  <bje@cygnus.com>

        * autoreconf.sh: Recognise -v as a synonym for --verbose.

1999-09-07  Gary V. Vaughan  <gvaughan@oranda.demon.co.uk>

        * Makefile.in (INSTALL, standards.info, autoconf.info):  MiKTeX
        for Windows treats all options after the first filename as
        additional filenames, so real options must appear before the first
        filename.

1999-09-07  Steven G. Johnson  <stevenj@alum.mit.edu>

        * autoconf.texi (LDFLAGS, LIBS): Document that -L linker flags
        should be kept in LDFLAGS and not LIBS.

1999-09-04  Scott Bambrough  <scottb@netwinder.org>

        * config.guess: Autodetect ArmLinux using 2.9.1.xx linker
        emulation names and using the emulation names from the linker from

        * acgeneral.m4 (AC_FOREACH_COMMA): New macro, to perform m4 loops
        on m4 lists (i.e., list='(item_1, item_2, ..., item_n)').
        (AC_FOREACH): New macro, to perform m4 loops on shell lists (i.e.,
        list='item_1 item_2 ... item_n').

        * acgeneral.m4 (AC_DEFUN): Now accept two other optionnal
        parameters: the name of the macro which is specialized here, and
        the name of the first argument.  For instance `AC_CHECK_FNMATCH'
        should be declared as specializing `AC_CHECK_FUNC' for `fnmatch'
        as first argument.

        * acgeneral.m4 (AC_CHECK_FILES): Use AC_FOREACH for looping,
        instead of the shell's loop.

        * acgeneral.m4 (AC_TR): In addition to transliteration, provide a
        means to specify the valid destination alphabet and a default
        character for aliens characters.  This is in order to remove
        characters such as `+:-' etc. that may appear in file names, but
        are not valid for shell variables or #defines.
        (AC_TR_DEFINE): New macro, maps anything to a valid uppercase
        #define rhs.
        (AC_TR_UPCASE_NAME): Replaced by AC_TR_DEFINE.  All callers
        changed.
        (AC_TR_UPCASE_FILE): Likewise.

        * acgeneral.m4 (AC_TR_SH): Don't use the generic AC_TR: there is a
        difficult problem of quoting between m4 and sh.  Use the variable
        $ac_tr_sh to work around this difficulty.
        (AC_VAR_TEST_SET): New macro, which tests if a variable is set.
        (AC_VAR_IF_SET): New `ifelse' macro.

        * autoreconf.sh: Do the right thing when AC_CONFIG_HEADER is
        given more than one filename. As noted in the "Invoking
        autoheader" node of the info files, autoheader will use the first
        file argument given to AC_CONFIG_HEADER. Prior to this patch,
        autoreconf would end up executing incorrect shell code (e.g.
        "test ! -f 1.h 2.h.in") in such cases.
        Patch submitted in parallel to bug-gnu-utils@prep.ai.mit.edu.

Wed Sep  3 23:00:44 1997  Chris Provenzano  <proven@cygnus.com>

        * configure : New configure generated by autoconf.
        * Makefile.in : Set SHELL=@SHELL@. configure now substiutes

        * acspecific.m4 (AC_FUNC_GETLOADAVG): Add a semicolon between
        shell variable assignments; the evaluation order varies between

        correctly even if they contain single quote, or are quoted by
        the shell.  From Paul Eggert.

        (AC_PROG_CC_GNU, AC_PROG_CC_G): Split out of AC_PROG_CC.
        (AC_PROG_CXX_GNU, AC_PROG_CXX_G): Split out of AC_PROG_CXX.
        For the *_G macros, make the cache variable names non-GNU-specific.
        (AC_C_CROSS): Mark obsolete, and otherwise a no-op.

        suggest AC_CHECK_HEADERS instead of AC_HEADER_STDC.

        * acgeneral.m4 (AC_INIT_PARSE_ARGS): Move initialization of
        ac_max_here_lines here from AC_OUTPUT_HEADER.

        * autoheader.sh: Take the multiple-include protection back out.
        It's not needed for a file that just #defines stuff, and, as Ken
        Raeburn pointed out in Apr 1994:
        Since you don't make it optional, and you don't give the writer of
        configure.in much control over the name of the symbol, it also would
        prevent one "config.h" file in a subdirectory from including
        "../config.h" as a way to avoid duplicating some common tests.

        * acspecific.m4 (AC_PROG_CC_WORKS, AC_PROG_CXX_WORKS): Don't try
        running a program, just try linking.
        (AC_C_CROSS): Make the wording clearer.

        compiler works before checking whether it's a GNU compiler.
        (AC_FUNC_VFORK): Call _exit after perror.
        (AC_PATH_XTRA): Go back to using -R, as setting an env var as part
        of CC doesn't get eval'd correctly to actually work.
        Directly test whether a space is needed after -R.
        Don't add "-L" to LDFLAGS if $x_libraries is empty.
        (AC_FUNC_STRFTIME): Check for it in -lintl only if it's not in the
        normal libraries.

        * Test release 2.10.3.

        * testsuite/Makefile.in (dejacheck): New target, suggested by Tom
        Tromey.

        conftest.subs into multiple files named conftest.s[1-9][0-9]*.
        Create a pipeline of sed commands that use these files, then delete
        the temporary files.  From John W. Eaton.

        * acspecific.m4 (AC_AIX, AC_MINIX): Remove warnings about AC_TRY_LINK.
        These macros don't change the linkage options.

        * Test release 2.10.2.

        * acspecific.m4 (AC_PROG_CC, AC_PROG_CXX) [GCC]: Use -O2 instead
        of -O.  Suggested by fnf@ninemoons.com (Fred Fish).

        * acgeneral.m4 (AC_OUTPUT_HEADER): Support passing
        AC_CONFIG_HEADER a value containing shell variables.  Suggested by
        Markku Savela and Julian Onions.
        * acgeneral.m4 (AC_TRY_RUN_NATIVE, AC_TRY_LINK, AC_TRY_COMPILE,
        AC_TRY_CPP): Show the test program in config.log if the test fails.
        From Karl Berry.

        * testsuite/config/unix.exp: Run the configure script as "./script"
        in case the user doesn't have "." in their PATH.

        * acgeneral.m4 (AC_TRY_COMPILE, AC_TRY_LINK): Deal with smart
        compilers that know that an unused function doesn't have to be
        linked in: call the function directly from main().
        (Removing a legacy from when they tried to run the code, I think-djm.)
        From fnf@ninemoons.com (Fred Fish).

        * acspecific.m4 (AC_FUNC_GETLOADAVG): Rename ac_save_LIBS to avoid
        a clash with AC_CHECK_LIB.
        From Jim Meyering.
        (AC_FUNC_FNMATCH, AC_FUNC_MMAP, AC_FUNC_VFORK, AC_FUNC_WAIT3,
        AC_FUNC_STRCOLL, AC_FUNC_MEMCMP): Rename cache variables to avoid
        wrong results if someone calls AC_CHECK_FUNC for these functions.

        * autoheader.sh: Don't cmp with config.h.in if it doesn't exist yet.
        Don't frob lines 1-@TOP@ or @BOTTOM@-end of acconfig.h's.
        Accept TAB as well as SPC after #undef in acconfig.h's.
