478 # depending on how configure is run. This is pretty annoying, since
479 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
480 # source directory, any form will work fine, but in subdirectories a
481 # relative path needs to be adjusted first.

488 # a relative $ac_aux_dir
490 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
491 # are both prefixed by $srcdir. In an in-source build this is usually
492 # harmless because $srcdir is '.', but things will broke when you
493 # start a VPATH build or use an absolute $srcdir.
495 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
496 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
497 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
