712# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
713# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
714# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
715#
716# Of course, Automake must honor this variable whenever it calls a
717# tool from the auxiliary directory.  The problem is that $srcdir (and
718# therefore $ac_aux_dir as well) can be either absolute or relative,
719# depending on how configure is run.  This is pretty annoying, since
720# it makes $ac_aux_dir quite unusable in subdirectories: in the top
721# source directory, any form will work fine, but in subdirectories a
722# relative path needs to be adjusted first.
723#
724# $ac_aux_dir/missing
725#    fails when called from a subdirectory if $ac_aux_dir is relative
726# $top_srcdir/$ac_aux_dir/missing
727#    fails if $ac_aux_dir is absolute,
728#    fails when called from a subdirectory in a VPATH build with
729#          a relative $ac_aux_dir
730#
731# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
732# are both prefixed by $srcdir.  In an in-source build this is usually
733# harmless because $srcdir is `.', but things will broke when you
734# start a VPATH build or use an absolute $srcdir.
735#
736# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
737# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
738#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
739# and then we would define $MISSING as
740#   MISSING="\${SHELL} $am_aux_dir/missing"
741# This will work as long as MISSING is not called from configure, because
742# unfortunately $(top_srcdir) has no meaning in configure.
743# However there are other variables, like CC, which are often used in
744# configure, and could therefore not use this "fixed" $ac_aux_dir.
745#
746# Another solution, used here, is to always expand $ac_aux_dir to an
747# absolute PATH.  The drawback is that using absolute paths prevent a
748# configured tree to be moved without reconfiguration.
