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

351: # relative path needs to be adjusted first.

357: # fails when called from a subdirectory in a VPATH build with

359: #
360: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir

362: # harmless because $srcdir is '.', but things will broke when you
363: # start a VPATH build or use an absolute $srcdir.
364: #
365: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,

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