1254# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets

1256# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
1257#
1258# Of course, Automake must honor this variable whenever it calls a
1259# tool from the auxiliary directory.  The problem is that $srcdir (and
1260# therefore $ac_aux_dir as well) can be either absolute or relative,
1261# depending on how configure is run.  This is pretty annoying, since
1262# it makes $ac_aux_dir quite unusable in subdirectories: in the top
1263# source directory, any form will work fine, but in subdirectories a
1264# relative path needs to be adjusted first.
1265#
1266# $ac_aux_dir/missing
1267#    fails when called from a subdirectory if $ac_aux_dir is relative
1268# $top_srcdir/$ac_aux_dir/missing
1269#    fails if $ac_aux_dir is absolute,
1270#    fails when called from a subdirectory in a VPATH build with
1271#          a relative $ac_aux_dir
1272#
1273# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
1274# are both prefixed by $srcdir.  In an in-source build this is usually
1275# harmless because $srcdir is `.', but things will broke when you
1276# start a VPATH build or use an absolute $srcdir.
1277#
1278# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
1279# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
1280#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
1281# and then we would define $MISSING as
1282#   MISSING="\${SHELL} $am_aux_dir/missing"
1283# This will work as long as MISSING is not called from configure, because
1284# unfortunately $(top_srcdir) has no meaning in configure.
1285# However there are other variables, like CC, which are often used in
1286# configure, and could therefore not use this "fixed" $ac_aux_dir.
1287#
1288# Another solution, used here, is to always expand $ac_aux_dir to an
1289# absolute PATH.  The drawback is that using absolute paths prevent a
