350: # it makes $ac_aux_dir quite unusable in subdirectories: in the top

352: # relative path needs to be adjusted first.

357: # fails if $ac_aux_dir is absolute,
358: # fails when called from a subdirectory in a VPATH build with

360: #
361: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
362: # are both prefixed by $srcdir. In an in-source build this is usually
363: # harmless because $srcdir is '.', but things will broke when you
364: # start a VPATH build or use an absolute $srcdir.
365: #
366: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,

368: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
