763# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
764# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
765# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
766#
767# Of course, Automake must honor this variable whenever it calls a
768# tool from the auxiliary directory.  The problem is that $srcdir (and
769# therefore $ac_aux_dir as well) can be either absolute or relative,
770# depending on how configure is run.  This is pretty annoying, since
771# it makes $ac_aux_dir quite unusable in subdirectories: in the top
772# source directory, any form will work fine, but in subdirectories a
773# relative path needs to be adjusted first.
774#
775# $ac_aux_dir/missing
776#    fails when called from a subdirectory if $ac_aux_dir is relative
777# $top_srcdir/$ac_aux_dir/missing
778#    fails if $ac_aux_dir is absolute,
779#    fails when called from a subdirectory in a VPATH build with
780#          a relative $ac_aux_dir
781#
782# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
783# are both prefixed by $srcdir.  In an in-source build this is usually
784# harmless because $srcdir is `.', but things will broke when you
785# start a VPATH build or use an absolute $srcdir.
786#
787# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
788# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
789#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
790# and then we would define $MISSING as
791#   MISSING="\${SHELL} $am_aux_dir/missing"
792# This will work as long as MISSING is not called from configure, because
793# unfortunately $(top_srcdir) has no meaning in configure.
794# However there are other variables, like CC, which are often used in
795# configure, and could therefore not use this "fixed" $ac_aux_dir.
796#
797# Another solution, used here, is to always expand $ac_aux_dir to an
798# absolute PATH.  The drawback is that using absolute paths prevent a
799# configured tree to be moved without reconfiguration.
