1193# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets

1195# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
1196#
1197# Of course, Automake must honor this variable whenever it calls a
1198# tool from the auxiliary directory.  The problem is that $srcdir (and
1199# therefore $ac_aux_dir as well) can be either absolute or relative,
1200# depending on how configure is run.  This is pretty annoying, since
1201# it makes $ac_aux_dir quite unusable in subdirectories: in the top
1202# source directory, any form will work fine, but in subdirectories a
1203# relative path needs to be adjusted first.
1204#
1205# $ac_aux_dir/missing
1206#    fails when called from a subdirectory if $ac_aux_dir is relative
1207# $top_srcdir/$ac_aux_dir/missing
1208#    fails if $ac_aux_dir is absolute,
1209#    fails when called from a subdirectory in a VPATH build with
1210#          a relative $ac_aux_dir
1211#
1212# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
1213# are both prefixed by $srcdir.  In an in-source build this is usually
1214# harmless because $srcdir is `.', but things will broke when you
1215# start a VPATH build or use an absolute $srcdir.
1216#
1217# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
1218# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
1219#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
1220# and then we would define $MISSING as
1221#   MISSING="\${SHELL} $am_aux_dir/missing"
1222# This will work as long as MISSING is not called from configure, because
1223# unfortunately $(top_srcdir) has no meaning in configure.
1224# However there are other variables, like CC, which are often used in
1225# configure, and could therefore not use this "fixed" $ac_aux_dir.
1226#
1227# Another solution, used here, is to always expand $ac_aux_dir to an
1228# absolute PATH.  The drawback is that using absolute paths prevent a
1229# configured tree to be moved without reconfiguration.
