196: # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
197: #
198: # Of course, Automake must honor this variable whenever it calls a
199: # tool from the auxiliary directory. The problem is that $srcdir (and
200: # therefore $ac_aux_dir as well) can be either absolute or relative,
201: # depending on how configure is run. This is pretty annoying, since
202: # it makes $ac_aux_dir quite unusable in subdirectories: in the top
203: # source directory, any form will work fine, but in subdirectories a
204: # relative path needs to be adjusted first.
205: #
206: # $ac_aux_dir/missing
207: # fails when called from a subdirectory if $ac_aux_dir is relative
208: # $top_srcdir/$ac_aux_dir/missing
209: # fails if $ac_aux_dir is absolute,
210: # fails when called from a subdirectory in a VPATH build with
211: # a relative $ac_aux_dir
212: #
213: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
214: # are both prefixed by $srcdir. In an in-source build this is usually
215: # harmless because $srcdir is `.', but things will broke when you
216: # start a VPATH build or use an absolute $srcdir.
217: #
218: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
219: # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
220: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
221: # and then we would define $MISSING as
222: # MISSING="\${SHELL} $am_aux_dir/missing"
223: # This will work as long as MISSING is not called from configure, because
224: # unfortunately $(top_srcdir) has no meaning in configure.
225: # However there are other variables, like CC, which are often used in
226: # configure, and could therefore not use this "fixed" $ac_aux_dir.
227: #
228: # Another solution, used here, is to always expand $ac_aux_dir to an
