7900 # serial 4 lt~obsolete.m4
7902 # These exist entirely to fool aclocal when bootstrapping libtool.
7903 #
7904 # In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
7905 # which have later been changed to m4_define as they aren't part of the
7906 # exported API, or moved to Autoconf or Automake where they belong.
7907 #
7908 # The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
7909 # in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
7910 # using a macro with the same name in our local m4/libtool.m4 it'll
7911 # pull the old libtool.m4 in (it doesn't see our shiny new m4_define
7912 # and doesn't know about Autoconf macros at all.)
7913 #
7914 # So we provide this file, which has a silly filename so it's always
7915 # included after everything else. This provides aclocal with the
7916 # AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
7917 # because those macros already exist, or will be overwritten later.
7918 # We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
7919 #
7920 # Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
7921 # Yes, that means every name once taken will need to remain here until
7922 # we give up compatibility with versions before 1.7, at which point
7923 # we need to keep only those names which we still refer to.
7925 # This is to help aclocal find these macros, as it can't see m4_define.

8368 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
8369 # $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
8370 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
8371 #
8372 # Of course, Automake must honor this variable whenever it calls a
8373 # tool from the auxiliary directory. The problem is that $srcdir (and
8374 # therefore $ac_aux_dir as well) can be either absolute or relative,
8375 # depending on how configure is run. This is pretty annoying, since
8376 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
8377 # source directory, any form will work fine, but in subdirectories a
8378 # relative path needs to be adjusted first.
8379 #
8380 # $ac_aux_dir/missing
8381 # fails when called from a subdirectory if $ac_aux_dir is relative
8382 # $top_srcdir/$ac_aux_dir/missing
8383 # fails if $ac_aux_dir is absolute,
8384 # fails when called from a subdirectory in a VPATH build with
8385 # a relative $ac_aux_dir
8386 #
8387 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
8388 # are both prefixed by $srcdir. In an in-source build this is usually
8389 # harmless because $srcdir is `.', but things will broke when you
8390 # start a VPATH build or use an absolute $srcdir.
8391 #
8392 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
8393 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
8394 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
8395 # and then we would define $MISSING as
8396 # MISSING="\${SHELL} $am_aux_dir/missing"
8397 # This will work as long as MISSING is not called from configure, because
8398 # unfortunately $(top_srcdir) has no meaning in configure.
8399 # However there are other variables, like CC, which are often used in
8400 # configure, and could therefore not use this "fixed" $ac_aux_dir.
8401 #
8402 # Another solution, used here, is to always expand $ac_aux_dir to an
8403 # absolute PATH. The drawback is that using absolute paths prevent a
