359: #
360: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
361: # are both prefixed by $srcdir. In an in-source build this is usually
1.1.1.3 ! misho 362: # harmless because $srcdir is '.', but things will broke when you
1.1 misho 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//*\(.*\)"`
