--- Comment #10 from Richard Guenther <rguenth at gcc dot gnu.org> 2012-01-03 13:29:56 UTC --- It's also questionable to cause new warnings to appear on the branch if you consider code using -Werror. Leaving open a bit for further consideration, should be closed as fixed for 4.7 once that is released and it didn't make the 4.6 branch.
