409 # therefore $ac_aux_dir as well) can be either absolute or relative,
410 # depending on how configure is run. This is pretty annoying, since
411 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
412 # source directory, any form will work fine, but in subdirectories a
413 # relative path needs to be adjusted first.
415 # $ac_aux_dir/missing

419 # fails when called from a subdirectory in a VPATH build with
420 # a relative $ac_aux_dir
422 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
423 # are both prefixed by $srcdir. In an in-source build this is usually
424 # harmless because $srcdir is '.', but things will broke when you
425 # start a VPATH build or use an absolute $srcdir.
427 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
428 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
429 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
