--- Comment #4 from Manuel López-Ibáñez <manu at gcc dot gnu.org> ---
Patches go to the gcc-patches mailing list for review. You will also need a
testcase formatted for inclusion on the testsuite and test your patch against
the GCC testsuite. See also: http://gcc.gnu.org/contribute.html

I don't see how your patch fixes this inconsistency.
