6209# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
6210# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
6211# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
6212#
6213# Of course, Automake must honor this variable whenever it calls a
6214# tool from the auxiliary directory.  The problem is that $srcdir (and
6215# therefore $ac_aux_dir as well) can be either absolute or relative,
6216# depending on how configure is run.  This is pretty annoying, since
6217# it makes $ac_aux_dir quite unusable in subdirectories: in the top
6218# source directory, any form will work fine, but in subdirectories a
6219# relative path needs to be adjusted first.
6220#
6221# $ac_aux_dir/missing
6222#    fails when called from a subdirectory if $ac_aux_dir is relative
6223# $top_srcdir/$ac_aux_dir/missing
6224#    fails if $ac_aux_dir is absolute,
6225#    fails when called from a subdirectory in a VPATH build with
6226#          a relative $ac_aux_dir
6227#
6228# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
6229# are both prefixed by $srcdir.  In an in-source build this is usually
6230# harmless because $srcdir is `.', but things will broke when you
6231# start a VPATH build or use an absolute $srcdir.
6232#
6233# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
6234# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
6235#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
6236# and then we would define $MISSING as
6237#   MISSING="\${SHELL} $am_aux_dir/missing"
6238# This will work as long as MISSING is not called from configure, because
6239# unfortunately $(top_srcdir) has no meaning in configure.
6240# However there are other variables, like CC, which are often used in
6241# configure, and could therefore not use this "fixed" $ac_aux_dir.
6242#
6243# Another solution, used here, is to always expand $ac_aux_dir to an
6244# absolute PATH.  The drawback is that using absolute paths prevent a
6245# configured tree to be moved without reconfiguration.
