--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> --- There are still 81 warnings on x86_64-linux at unique spots during bootstrap more than a year after the warning has been added, and at least several of those aren't really bugs in the code, so the question is if we want to slow things down by adding workarounds for the warning.
