290: #
291: # Of course, Automake must honor this variable whenever it calls a
292: # tool from the auxiliary directory. The problem is that $srcdir (and
293: # therefore $ac_aux_dir as well) can be either absolute or relative,
294: # depending on how configure is run. This is pretty annoying, since
295: # it makes $ac_aux_dir quite unusable in subdirectories: in the top
296: # source directory, any form will work fine, but in subdirectories a
297: # relative path needs to be adjusted first.
298: #
299: # $ac_aux_dir/missing
300: # fails when called from a subdirectory if $ac_aux_dir is relative
301: # $top_srcdir/$ac_aux_dir/missing
302: # fails if $ac_aux_dir is absolute,
303: # fails when called from a subdirectory in a VPATH build with
304: # a relative $ac_aux_dir
305: #
306: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
307: # are both prefixed by $srcdir. In an in-source build this is usually
308: # harmless because $srcdir is '.', but things will broke when you
309: # start a VPATH build or use an absolute $srcdir.
310: #
311: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
312: # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
313: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
314: # and then we would define $MISSING as
315: # MISSING="\${SHELL} $am_aux_dir/missing"
316: # This will work as long as MISSING is not called from configure, because
317: # unfortunately $(top_srcdir) has no meaning in configure.
318: # However there are other variables, like CC, which are often used in
319: # configure, and could therefore not use this "fixed" $ac_aux_dir.
320: #
321: # Another solution, used here, is to always expand $ac_aux_dir to an
