182 # $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
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
