    289 # depending on how configure is run.  This is pretty annoying, since
    290 # it makes $ac_aux_dir quite unusable in subdirectories: in the top

    299 #          a relative $ac_aux_dir
    300 #

    302 # are both prefixed by $srcdir.  In an in-source build this is usually
    303 # harmless because $srcdir is '.', but things will broke when you
    304 # start a VPATH build or use an absolute $srcdir.
    305 #
    306 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
    307 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
    308 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
