346 #
347 # Of course, Automake must honor this variable whenever it calls a
348 # tool from the auxiliary directory. The problem is that $srcdir (and
349 # therefore $ac_aux_dir as well) can be either absolute or relative,
350 # depending on how configure is run. This is pretty annoying, since
351 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
352 # source directory, any form will work fine, but in subdirectories a
353 # relative path needs to be adjusted first.
354 #
355 # $ac_aux_dir/missing
356 # fails when called from a subdirectory if $ac_aux_dir is relative
357 # $top_srcdir/$ac_aux_dir/missing
358 # fails if $ac_aux_dir is absolute,
359 # fails when called from a subdirectory in a VPATH build with
360 # a relative $ac_aux_dir
361 #
362 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
363 # are both prefixed by $srcdir. In an in-source build this is usually
364 # harmless because $srcdir is '.', but things will broke when you
365 # start a VPATH build or use an absolute $srcdir.
366 #
367 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
368 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
369 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
370 # and then we would define $MISSING as
371 # MISSING="\${SHELL} $am_aux_dir/missing"
372 # This will work as long as MISSING is not called from configure, because
373 # unfortunately $(top_srcdir) has no meaning in configure.
374 # However there are other variables, like CC, which are often used in
375 # configure, and could therefore not use this "fixed" $ac_aux_dir.
376 #
