199# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
200# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
201# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
202#
203# Of course, Automake must honor this variable whenever it calls a
204# tool from the auxiliary directory.  The problem is that $srcdir (and
205# therefore $ac_aux_dir as well) can be either absolute or relative,
206# depending on how configure is run.  This is pretty annoying, since
207# it makes $ac_aux_dir quite unusable in subdirectories: in the top
208# source directory, any form will work fine, but in subdirectories a
209# relative path needs to be adjusted first.
210#
211# $ac_aux_dir/missing
212#    fails when called from a subdirectory if $ac_aux_dir is relative
213# $top_srcdir/$ac_aux_dir/missing
214#    fails if $ac_aux_dir is absolute,
215#    fails when called from a subdirectory in a VPATH build with
216#          a relative $ac_aux_dir
217#
218# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
219# are both prefixed by $srcdir.  In an in-source build this is usually
220# harmless because $srcdir is `.', but things will broke when you
221# start a VPATH build or use an absolute $srcdir.
222#
223# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
224# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
225#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
226# and then we would define $MISSING as
227#   MISSING="\${SHELL} $am_aux_dir/missing"
228# This will work as long as MISSING is not called from configure, because
229# unfortunately $(top_srcdir) has no meaning in configure.
230# However there are other variables, like CC, which are often used in
231# configure, and could therefore not use this "fixed" $ac_aux_dir.
232#
233# Another solution, used here, is to always expand $ac_aux_dir to an
234# absolute PATH.  The drawback is that using absolute paths prevent a
235# configured tree to be moved without reconfiguration.
