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

749# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
750#
751# Of course, Automake must honor this variable whenever it calls a
752# tool from the auxiliary directory. The problem is that $srcdir (and
753# therefore $ac_aux_dir as well) can be either absolute or relative,
754# depending on how configure is run. This is pretty annoying, since
755# it makes $ac_aux_dir quite unusable in subdirectories: in the top
756# source directory, any form will work fine, but in subdirectories a
757# relative path needs to be adjusted first.
758#
759# $ac_aux_dir/missing
760# fails when called from a subdirectory if $ac_aux_dir is relative
761# $top_srcdir/$ac_aux_dir/missing
762# fails if $ac_aux_dir is absolute,
763# fails when called from a subdirectory in a VPATH build with
764# a relative $ac_aux_dir
765#
766# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
767# are both prefixed by $srcdir. In an in-source build this is usually
768# harmless because $srcdir is '.', but things will broke when you
769# start a VPATH build or use an absolute $srcdir.
770#
771# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
772# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
773# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
774# and then we would define $MISSING as
775# MISSING="\${SHELL} $am_aux_dir/missing"
776# This will work as long as MISSING is not called from configure, because
777# unfortunately $(top_srcdir) has no meaning in configure.
778# However there are other variables, like CC, which are often used in
779# configure, and could therefore not use this "fixed" $ac_aux_dir.
780#
781# Another solution, used here, is to always expand $ac_aux_dir to an
