6072# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
6073# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
6074# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
6075#
6076# Of course, Automake must honor this variable whenever it calls a
6077# tool from the auxiliary directory.  The problem is that $srcdir (and
6078# therefore $ac_aux_dir as well) can be either absolute or relative,
6079# depending on how configure is run.  This is pretty annoying, since
6080# it makes $ac_aux_dir quite unusable in subdirectories: in the top
6081# source directory, any form will work fine, but in subdirectories a
6082# relative path needs to be adjusted first.
6083#
6084# $ac_aux_dir/missing
6085#    fails when called from a subdirectory if $ac_aux_dir is relative
6086# $top_srcdir/$ac_aux_dir/missing
6087#    fails if $ac_aux_dir is absolute,
6088#    fails when called from a subdirectory in a VPATH build with
6089#          a relative $ac_aux_dir
6090#
6091# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
6092# are both prefixed by $srcdir.  In an in-source build this is usually
6093# harmless because $srcdir is `.', but things will broke when you
6094# start a VPATH build or use an absolute $srcdir.
6095#
6096# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
6097# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
6098#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
6099# and then we would define $MISSING as
6100#   MISSING="\${SHELL} $am_aux_dir/missing"
6101# This will work as long as MISSING is not called from configure, because
6102# unfortunately $(top_srcdir) has no meaning in configure.
6103# However there are other variables, like CC, which are often used in
6104# configure, and could therefore not use this "fixed" $ac_aux_dir.
6105#
6106# Another solution, used here, is to always expand $ac_aux_dir to an
6107# absolute PATH.  The drawback is that using absolute paths prevent a
6108# configured tree to be moved without reconfiguration.
