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

277: # relative path needs to be adjusted first.

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

285: #
286: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir

288: # harmless because $srcdir is '.', but things will broke when you
289: # start a VPATH build or use an absolute $srcdir.
290: #
291: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
292: # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
293: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
