10035 # The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
10036 # in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
10037 # using a macro with the same name in our local m4/libtool.m4 it'll
10038 # pull the old libtool.m4 in (it doesn't see our shiny new m4_define
10039 # and doesn't know about Autoconf macros at all.)
10040 #
10041 # So we provide this file, which has a silly filename so it's always
10042 # included after everything else.  This provides aclocal with the
10043 # AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
10044 # because those macros already exist, or will be overwritten later.
10045 # We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.

10047 # Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
10048 # Yes, that means every name once taken will need to remain here until
10049 # we give up compatibility with versions before 1.7, at which point
10050 # we need to keep only those names which we still refer to.

10199 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets

10201 # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
10202 #
10203 # Of course, Automake must honor this variable whenever it calls a
10204 # tool from the auxiliary directory.  The problem is that $srcdir (and
10205 # therefore $ac_aux_dir as well) can be either absolute or relative,
10206 # depending on how configure is run.  This is pretty annoying, since
10207 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
10208 # source directory, any form will work fine, but in subdirectories a
10209 # relative path needs to be adjusted first.
10210 #
10211 # $ac_aux_dir/missing
10212 #    fails when called from a subdirectory if $ac_aux_dir is relative
10213 # $top_srcdir/$ac_aux_dir/missing
10214 #    fails if $ac_aux_dir is absolute,
10215 #    fails when called from a subdirectory in a VPATH build with
10216 #          a relative $ac_aux_dir
10217 #
10218 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
10219 # are both prefixed by $srcdir.  In an in-source build this is usually
10220 # harmless because $srcdir is '.', but things will broke when you
10221 # start a VPATH build or use an absolute $srcdir.
10222 #
10223 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
10224 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
10225 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
10226 # and then we would define $MISSING as
10227 #   MISSING="\${SHELL} $am_aux_dir/missing"
10228 # This will work as long as MISSING is not called from configure, because
10229 # unfortunately $(top_srcdir) has no meaning in configure.
10230 # However there are other variables, like CC, which are often used in
10231 # configure, and could therefore not use this "fixed" $ac_aux_dir.
10232 #
10233 # Another solution, used here, is to always expand $ac_aux_dir to an
10234 # absolute PATH.  The drawback is that using absolute paths prevent a
