Wed Jul  7 14:37:35 1993  David J. MacKenzie  (djm@goldman.gnu.ai.mit.edu)

        * autoheader.sh (--help): Print help message to stdout and exit 0.
        (--version): Exit after printing version number.
        * autoconf.sh (--version): Exit after printing version number.

        * acspecific.m4 (AC_LONG_DOUBLE): Make sure that long double
        isn't smaller than double, as in Ultrix 4.[23] cc.

        * acgeneral.m4 (AC_REPLACE_FUNCS): Include ctype.h in the test
        program to get stubs.

        * acspecific.m4 (AC_FIND_X): New macro.

Tue Jul  6 19:15:17 1993  David J. MacKenzie  (djm@goldman.gnu.ai.mit.edu)

        * acspecific.m4 (AC_GETLOADAVG): Try ls -L first, in case
        /dev/kmem is a symlink (as on Solaris).

Wed Jun 30 22:08:22 1993  Noah Friedman  (friedman@nutrimat.gnu.ai.mit.edu)

        * acspecific.m4 (AC_MINUS_C_MINUS_O): Remove spurious `then'.

Fri Jun 25 23:16:42 1993  Paul Eggert  (eggert@twinsun.com)

        * acspecific.m4 (AC_CONST): Replace `p = <const char** expr>'
        with `ccp = <const char** expr>'; the former wasn't ANSI C, and
        was causing working compilers to be rejected.

Fri Jun 25 13:26:34 1993  Noah Friedman  (friedman@nutrimat.gnu.ai.mit.edu)

        * acspecific.m4 (AC_LONG_FILE_NAMES): Redirect rm's stderr to
        /dev/null.

Thu Jun 24 15:58:04 1993  Noah Friedman  (friedman@nutrimat.gnu.ai.mit.edu)

        * autoconf.sh, autoheader.sh, acgeneral.m4 (AC_PREPARE): Undo
        change of Jun 16 1993.  Only set `LANG' and `LC_ALL' to "C" if
        already set.

Sat Jun 19 00:01:51 1993  Jim Meyering  (meyering@comco.com)

        * acgeneral.m4: Undefine m4's `format' builtin.
        * acspecific.m4 (AC_HAVE_POUNDBANG): Make conftest executable,
        but not necessarily writable by group or other.

Thu Jun 17 21:10:33 1993  Noah Friedman  (friedman@nutrimat.gnu.ai.mit.edu)

        * acspecific.m4 (AC_PROG_CPP): Put double quotes around ${CC-cc},
        not single quotes.
        If --verbose option given, say what CPP is being set to.

Wed Jun 16 17:50:00 1993  Jim Blandy  (jimb@wookumz.gnu.ai.mit.edu)

        * acspecific.m4 (AC_PROG_CPP): Make sure that `cc -E` doesn't
        run the program through the C compiler too.  Bob Olson
        <olson@mcs.anl.gov> says it does on the NeXT.

Wed Jun 16 16:17:05 1993  Noah Friedman  (friedman@nutrimat.gnu.ai.mit.edu)

        * autoconf.sh, autoheader.sh, acgeneral.m4 (AC_PREPARE): Always set
        `LANG' and `LC_ALL' environment variables to `C'.

Fri Jun 11 14:29:31 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * acspecific.m4 (AC_MINUS_C_MINUS_O): Test that cc works at all,
        and only test it for -c -o if it does.

Tue Jun  8 01:47:22 1993  Paul Eggert  (eggert@twinsun.com)

        * acgeneral.m4 (AC_OUTPUT): The line
          DEFS="`echo \"$DEFS\" | sed 's%[&\\\]%\\\&%g'`"
        doesn't work in some shells, which don't allow nesting
        \"\" inside `` inside "", and which don't unescape \\\& in the
        expected (?) way.  Also, some versions of echo interpret
        backslashes inside $DEFS.  Put $DEFS into a temporary file
        to avoid these portability minefields.

Mon Jun  7 20:11:50 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * acspecific.m4 (AC_GETLOADAVG): In setting KMEM_GROUP, use new sed
        magic from friedman which should win with both meanings of ls -lg.

Mon Jun  7 06:48:49 1993  Noah Friedman  (friedman@nutrimat.gnu.ai.mit.edu)

        * Makefile.in (dist): Change gzipped tar file extension to `.gz'.
        Use explicit --gzip option to tar to make sure tar uses the right
        compression program (or else exits from failure to understand the
        option).

        * acgeneral.m4 (AC_OUTPUT): Don't split sed expr for exec_prefix
        across two lines, since not all versions of sed understand that.

        * acspecific.m4 (AC_HAVE_POUNDBANG): Complete rewrite which doesn't
        depend on csh.

Tue Jun  1 03:06:28 1993  Noah Friedman  (friedman@nutrimat.gnu.ai.mit.edu)

        * Version 1.4.1 (not announced to the general public, but
        a snapshot was put on the June '93 GNU CDROM).

        * Makefile.in (dist): If ln fails (e.g. because of cross-device
        links), mention on stdout that file is being copied.

        * acgeneral.m4 (AC_PREPARE): Use `[$]*' in assignment to
        configure_args to get shell positional args, rather than m4 args to
        AC_PREPARE.
        (AC_OUTPUT): Use `configure_args' in config.status
        when invoked with --recheck, rather than $*.

Mon May 31 13:12:56 1993  Paul Eggert  (eggert@twinsun.com)

        * acspecific.m4 (AC_LONG_FILE_NAMES): rm $dir/conftest*,
        not conftest*.

Mon May 31 04:18:18 1993  Roland McGrath  (friedman@nutrimat.gnu.ai.mit.edu)

        * acgeneral.m4 (AC_HAVE_LIBRARY): Quote libname in define.

Sun May 30 19:52:24 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * acspecific.m4 (AC_SETVBUF_REVERSED): Pass (char *) main to
        setvbuf instead of zero.

Thu May 27 20:30:53 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * acgeneral.m4 (AC_PREPARE): Save $* in shell var `configure_args'.
        (AC_OUTPUT): Use $configure_args in place of $*.

Wed May 26 16:19:51 1993  Noah Friedman  (friedman@nutrimat.gnu.ai.mit.edu)

        * autoconf.texi (AC_PROG_INSTALL): Doc fix.
        (Automatic Remaking): Put code fragment in @example ... @end example.

Mon May 24 15:46:47 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * autoheader.sh (frob): Redefine AC_CONFIG_HEADER to set shell
        variable `config_h'.
        (config_h): New variable, initialize to "config.h" before frobbing.
        (final output): Write ${config_h}.in.

Sat May 22 17:45:19 1993  Noah Friedman  (friedman@nutrimat.gnu.ai.mit.edu)

        * Version 1.4 released.

Thu May 20 20:25:45 1993  Jim Blandy  (jimb@geech.gnu.ai.mit.edu)

        * acgeneral.m4 (AC_IDENTITY): New function.
        (AC_DEFINE_UNQUOTED): Use it to fix this; due to a
        misunderstanding of m4, this was using its first argument as
        the definition.

Thu May 20 09:21:55 1993  Jim Meyering  (meyering@comco.com)

        * acspecific.m4 (AC_ALLOCA) [find_stack_direction]: Return the
        value from the recursive call.  If it worked before, it was by luck.
        From Bruno Haible <haible@ma2s2.mathematik.uni-karlsruhe.de>.

Tue May 18 23:40:21 1993  Noah Friedman  (friedman@nutrimat.gnu.ai.mit.edu)

        * acspecific.m4 (AC_STDC_HEADERS): Require AC_PROG_CPP.

Mon May 17 18:01:09 1993  Karl Berry  (karl@hal.gnu.ai.mit.edu)

        * acgeneral.m4 (AC_OUTPUT): Use variables gen_files and
        gen_config in the loop that generates the output (Make)files,
        instead of hardwiring the filenames.

Sat May 15 17:23:19 1993  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

        * autoconf.sh: Accept `-' to mean read stdin as input.
        * autoheader.sh: Likewise.

Fri May 14 12:41:02 1993  Noah Friedman  (friedman@nutrimat.gnu.ai.mit.edu)

        * autoheader.sh, acspecific.m4 (AC_PREPARE): If `LANG' environment
        variable is set, reset its value to `C'.  This is so `tr [...]'
        works more portably.

Thu May 13 22:56:20 1993  Paul Eggert  (eggert@twinsun.com)

        * acspecific.m4 (VOID_CLOSEDIR): Test closedir instead of assuming
        that it works.  E.g. dynix closedir yields garbage, but has no
        prototype.  Presumably Xenix closedir had the same problem, so
        stop special-casing it.

Wed May 12 20:25:36 1993  Jim Meyering  (meyering@comco.com)

        * acconfig.h: Add HAVE_LONG_DOUBLE.

Wed May 12 15:07:36 1993  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

        * acgeneral.m4 (AC_DEFINE_UNQUOTED): New macro.

        * acgeneral.m4 (AC_FUNC_CHECK): Include ctype.h instead of stdio.h.
        We want it only to define __stub_* in glibc.  Using stdio.h lost
        when it contained a conflicting prototype for $1; ctype.h has fewer
        prototypes.

        * acconfig.h: Add GETGROUPS_T.

        * acspecific.m4 (AC_PROG_RANLIB): Use : instead of @: for no-op.
        Some braindead make does bizarre magical things with @ in variables.

Mon May 10 14:24:27 1993  Noah Friedman  (friedman@nutrimat.gnu.ai.mit.edu)

        * acspecific.m4 (AC_HAVE_POUNDBANG): New feature.

        * acgeneral.m4 (AC_OUTPUT): Add more backslashes to character class
        in DEFS filter (sigh).

Sun May  9 14:04:31 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * acgeneral.m4 (AC_DEFINE_QUOTE): No AC_QUOTE_SED (was innermost).
        (AC_HEADER_EGREP, AC_PROGRAM_EGREP, AC_TEST_CPP): Put a \ before
        $DEFS in string to be evalled.
        (AC_OUTPUT): Run DEFS through a sed filter that quotes things in it
        from sed (woo woo!) before writing it into config.status.

        * acspecific.m4 (AC_ALLOCA): Use AC_PROGRAM_EGREP to test for [CRAY
        && !CRAY2], instead of AC_TEST_PROGRAM.  No need to run a program
        for this.

        * acgeneral.m4 (AC_PROGRAM_CHECK): Extract the first word of $2
        when looking for it in PATH, so it can be a program name with args.
        Omit default assignment if $4 is empty.
        Only write verbose msg if $1 was set nonempty.
        * acspecific.m4 (AC_PROG_YACC): Pass 'bison -y' (quoted like that)
        in list to AC_PROGRAMS_CHECK.  Don't test for bison later to add -y
        flag.

Sat May  8 00:23:58 1993  Jim Meyering  (meyering@comco.com)

        * acgeneral.m4 (AC_REPLACE_FUNCS): Add a trailing newline in
        code for AC_COMPILE_CHECK.  Otherwise it got spurious failures.

        * acspecific.m4 (TIME_WITH_SYS_TIME): New macro.

        * Makefile.in (dist): Depend on Makefile.  Use gzip instead
        of compress.  Link files individually instead of en masse;
        if a link fails, use `cp -f' on the losing file.

        * acspecific.m4 (AC_ALLOCA): Define CRAY_STACKSEG_END (the
        name of a function used in alloca.c) for CRAY-1, CRAY X-MP,
        and CRAY Y-MP.

Fri May  7 15:56:26 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * acspecific.m4 (AC_GETLOADAVG): Check for mach/mach.h, but don't
        disable nlist checks if found.

Fri May  7 04:59:25 1993  Noah Friedman  (friedman@nutrimat.gnu.ai.mit.edu)

        * acspecific.m4 (AC_PROG_INSTALL): Don't look for `install' in
        /usr/ucb.

Thu May  6 20:41:35 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * acgeneral.m4 (AC_FUNC_CHECK): The test program should choke on
        #ifdef __stub___$1 as well.
        (AC_REPLACE_FUNCS): Make the test program choke on stubs.

Wed May  5 20:43:13 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * autoconf.sh ($infile existence check): Fixed test for
        nonemptiness of $print_version to not always be true.

Wed May  5 17:22:42 1993  David J. MacKenzie  (djm@wookumz.gnu.ai.mit.edu)

        * acgeneral.m4 (AC_PREFIX, AC_PROGRAM_CHECK), acspecific.m4
        (AC_PROG_INSTALL): If IFS wasn't set initially, give it a
        normal default value.  Happens on LynxOS (x86), says
        Pete Klammer <PKLAMMER@cudnvr.denver.colorado.edu>.

Wed May  5 13:22:52 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * acgeneral.m4: Undefine the `shift' builtin.

        * acspecific.m4 (AC_PROG_YACC): Use AC_PROGRAMS_CHECK to check for
        both bison and yacc, instead of two AC_PROGRAM_CHECK uses.

        * autoheader.sh ($# -eq 0): Set var $tmpout to name of temp file,
        send stdout there instead of config.h.in.
        (just before exit): If $# -eq 0, then move $tmpout to config.h.in
        if $status -eq 0, or remove $tmpout otherwise.

        * acspecific.m4 (AC_STRCOLL): Rewritten to use a test program that
        verifies that `strcoll' does vaguely reasonable ordering.

Tue May  4 19:59:00 1993  Jim Meyering  (meyering@comco.com)

        * acspecific.m4 (AC_LONG_DOUBLE): Don't explicitely echo
        `checking for long double'.

Mon May  3 22:04:35 1993  Jim Meyering  (meyering@comco.com)

        * acspecific.m4 (AC_GETGROUPS_T): New macro.

Sat May  1 22:37:55 1993  Jim Meyering  (meyering@comco.com)

Thu Apr 22 18:24:40 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * acgeneral.m4 (AC_FUNC_CHECK): Remove spurious `#endif' line at end.

        * acgeneral.m4 (AC_WITH): Fix reversed args to patsubst.
        Test $with_FOO, not $FOO.

Wed Apr 21 18:14:19 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * acgeneral.m4 (AC_QUOTE_TOKEN): New macro.
        (AC_DEFINE_QUOTE): Use it.

Tue Apr 20 18:02:46 1993  Noah Friedman  (friedman@nutrimat.gnu.ai.mit.edu)

        * acspecific.m4 (AC_DECLARE_YYTEXT): Guess name of lex output file
        and do AC_SUBST of `LEX_OUTPUT_ROOT'.
        Add `dnl' after calling some autoconf macros.

Mon Apr 19 15:46:24 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * acspecific.m4 (AC_MINUS_C_MINUS_O): Do each compile a second time
        after testing for the existence of the output.  Some compilers
        refuse to overwrite an existing .o file with -o, though they will
        create one.

        * acspecific.m4 (AC_DECLARE_YYTEXT): Changed lex input to two lines
        of "%%", not just one.

Sat Apr 17 17:26:12 1993  Jim Meyering  (meyering@comco.com)

        * acgeneral.m4 (AC_COMPILE_CHECK): Don't print `checking for ...'
        message if first argument is empty.

Sat Apr 17 01:18:41 1993  Noah Friedman  (friedman@nutrimat.gnu.ai.mit.edu)

        * acspecific.m4 (AC_PID_T): provide self.
        (AC_VFORK): Require AC_PID_T.

Fri Apr 16 11:57:35 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * acgeneral.m4 (AC_PROGRAMS_CHECK): Take optional third arg; if
        given, use it as the default value.

Thu Apr 15 16:43:45 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * acgeneral.m4 (AC_REPLACE_FUNCS): Print a message under --verbose.

        * acgeneral.m4 (AC_HAVE_LIBRARY): Use m4's patsubst and translit
        instead of running sed and tr at runtime.

        program to define STACK_DIRECTION.

Mon Apr  5 19:02:52 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * acspecific.m4 (AC_LONG_FILE_NAMES): Put test inside a for loop on
        several directories: . /tmp $prefix $exec_prefix.  Define
        HAVE_LONG_FILE_NAMES iff long names win in all those directories.

Sun Apr  4 18:38:23 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * Makefile.in (%.info): Removed pattern rule.

        * acspecific.m4 (AC_CONST): Uncomment and fix second AIX test.

Wed Mar 31 16:58:12 1993  Roland McGrath  (roland@geech.gnu.ai.mit.edu)

        * acspecific.m4 (AC_CONST): Rewrite first AIX XL C 1.02.0.0 test.
        Comment out bogosity in second AIX test.

Wed Mar 31 12:45:59 1993  Jim Meyering  (meyering@comco.com)

        * acgeneral.m4 (AC_DEFINE): Put single quotes around definition
        that is echoed with --verbose.  AC_DEFINE(MVDIR, "$(libdir)/mvdir")
        was generating losing code.

Mon Mar 29 15:44:24 1993  David J. MacKenzie  (djm@kropotkin.gnu.ai.mit.edu)

        * acspecific.m4 (AC_STDC_HEADERS): Add a missing pair of [quotes].

        * acspecific.m4 (AC_CONST): Remove single quotes from the C
        program; they produce shell syntax errors.

        * acgeneral.m4 (AC_DEFINE): Add a newline after "}" to prevent
        commands following on the same line of configure.in from
        generating shell syntax errors.

        * acgeneral.m4 (AC_COMPILE_CHECK): Use explicit return types
        to avoid warnings.
        (AC_TEST_CPP): Add parens to force redirection order.
        (AC_OUTPUT): Allow hostname to return bogus exit status.
        From Jean-loup Gailly <jloup@chorus.fr>.

Mon Mar 22 16:53:01 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * autoconf.sh: Use $M4, not m4 explicitly.
        (M4): If unset in env, initialize to @m4@.
        * autoheader.sh: Likewise.
        * Makefile.in (M4): Define new variable.
        (autoconf.conf, %.conf): Use it.
        (editsh): New variable: sed command to replace @datadir@; also
        replace @M4@ with $(M4).
        (autoconf, autoheader): Use $(editsh) instead of explicit sed command.

Mon Mar 22 13:08:10 1993  Jim Meyering  (meyering@comco.com)

        * acspecific.m4 (AC_CONST): IBM's /bin/cc under AIX-3.2 on an rs6000
        rejects attempts to modify *any* member of a struct that has a
        member declared like `const int *ap[2]'.

Wed Mar 17 18:08:30 1993  Noah Friedman  (friedman@nutrimat.gnu.ai.mit.edu)

        * autoconf.sh, autoheader.sh (MACRODIR): Variable renamed to
        AC_MACRODIR.  Don't initialize it at runtime if it is already set
        in the environment.
        (MACROFILES): Don't set until after options are processed.
        (print_version): New temp variable.

        * autoconf.sh, autoheader.sh: Rewrote argument parsing.
        Added `-m', `--macrodir', `-h', `--help', and `--' options.
        Updated usage string.

        (AC_SIZE_T): Define size_t to be unsigned, not int, for
        ANSI-friendliness.

        dwarf.h too.

        * autoconf.sh: Exit with status 1 if there are unresolved macros.
