181     # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets

183     # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
184     #
185     # Of course, Automake must honor this variable whenever it calls a
186     # tool from the auxiliary directory. The problem is that $srcdir (and
187     # therefore $ac_aux_dir as well) can be either absolute or relative,
188     # depending on how configure is run. This is pretty annoying, since
189     # it makes $ac_aux_dir quite unusable in subdirectories: in the top
190     # source directory, any form will work fine, but in subdirectories a
191     # relative path needs to be adjusted first.
192     #
193     # $ac_aux_dir/missing
194     # fails when called from a subdirectory if $ac_aux_dir is relative
195     # $top_srcdir/$ac_aux_dir/missing
196     # fails if $ac_aux_dir is absolute,
197     # fails when called from a subdirectory in a VPATH build with
198     # a relative $ac_aux_dir
199     #
200     # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
201     # are both prefixed by $srcdir. In an in-source build this is usually
202     # harmless because $srcdir is `.', but things will broke when you
203     # start a VPATH build or use an absolute $srcdir.
204     #
205     # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
206     # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
207     # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
208     # and then we would define $MISSING as
209     # MISSING="\${SHELL} $am_aux_dir/missing"
210     # This will work as long as MISSING is not called from configure, because
211     # unfortunately $(top_srcdir) has no meaning in configure.
212     # However there are other variables, like CC, which are often used in
213     # configure, and could therefore not use this "fixed" $ac_aux_dir.
214     #
215     # Another solution, used here, is to always expand $ac_aux_dir to an
216     # absolute PATH. The drawback is that using absolute paths prevent a
