232# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
233# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
234# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
235#
236# Of course, Automake must honor this variable whenever it calls a
237# tool from the auxiliary directory.  The problem is that $srcdir (and
238# therefore $ac_aux_dir as well) can be either absolute or relative,
239# depending on how configure is run.  This is pretty annoying, since
240# it makes $ac_aux_dir quite unusable in subdirectories: in the top
241# source directory, any form will work fine, but in subdirectories a
242# relative path needs to be adjusted first.
243#
244# $ac_aux_dir/missing
245#    fails when called from a subdirectory if $ac_aux_dir is relative
246# $top_srcdir/$ac_aux_dir/missing
247#    fails if $ac_aux_dir is absolute,
248#    fails when called from a subdirectory in a VPATH build with
249#          a relative $ac_aux_dir
250#
251# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
252# are both prefixed by $srcdir.  In an in-source build this is usually
253# harmless because $srcdir is `.', but things will broke when you
254# start a VPATH build or use an absolute $srcdir.
255#
256# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
257# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
258#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
259# and then we would define $MISSING as
260#   MISSING="\${SHELL} $am_aux_dir/missing"
261# This will work as long as MISSING is not called from configure, because
262# unfortunately $(top_srcdir) has no meaning in configure.
263# However there are other variables, like CC, which are often used in
264# configure, and could therefore not use this "fixed" $ac_aux_dir.
265#
266# Another solution, used here, is to always expand $ac_aux_dir to an
267# absolute PATH.  The drawback is that using absolute paths prevent a
268# configured tree to be moved without reconfiguration.
