--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed. Looks like it has been broken since states_num was added in
r0-47017-g30028c85159c12 which was in GCC 3.4.0 but the warning (with -Werror)
didn't come in much later until -Wunused-but-set-variable was added in
r0-99233-gebfbbdc556443d for GCC 4.6.0.

So this is a regression, an old one even.
