["rwild at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #11 from rwild at gcc dot gnu dot org  2008-07-07 18:55 -------
The reported failure is fixed.  However, building with --enable-maintainer-mode
still fails due to this error, already described in
<http://gcc.gnu.org/ml/gcc-patches/2008-07/msg00452.html>:
