222# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
223# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
224# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
225#
226# Of course, Automake must honor this variable whenever it calls a
227# tool from the auxiliary directory.  The problem is that $srcdir (and
228# therefore $ac_aux_dir as well) can be either absolute or relative,
229# depending on how configure is run.  This is pretty annoying, since
230# it makes $ac_aux_dir quite unusable in subdirectories: in the top
231# source directory, any form will work fine, but in subdirectories a
232# relative path needs to be adjusted first.
233#
234# $ac_aux_dir/missing
235#    fails when called from a subdirectory if $ac_aux_dir is relative
236# $top_srcdir/$ac_aux_dir/missing
237#    fails if $ac_aux_dir is absolute,
238#    fails when called from a subdirectory in a VPATH build with
239#          a relative $ac_aux_dir
240#
241# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
242# are both prefixed by $srcdir.  In an in-source build this is usually
243# harmless because $srcdir is `.', but things will broke when you
244# start a VPATH build or use an absolute $srcdir.
245#
246# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
247# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
248#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
249# and then we would define $MISSING as
250#   MISSING="\${SHELL} $am_aux_dir/missing"
251# This will work as long as MISSING is not called from configure, because
252# unfortunately $(top_srcdir) has no meaning in configure.
253# However there are other variables, like CC, which are often used in
254# configure, and could therefore not use this "fixed" $ac_aux_dir.
255#
256# Another solution, used here, is to always expand $ac_aux_dir to an
257# absolute PATH.  The drawback is that using absolute paths prevent a
258# configured tree to be moved without reconfiguration.
