--- Comment #22 from Florian Weimer <fw at gcc dot gnu.org> --- (In reply to Marek Polacek from comment #21) > The testcase in Comment 14 should now compile fine. What's the best way to detect that a compiler has this fix? We cannot use a configure check. Is there anything better than looking at __GNUC__? Are you going to backport this fix? Thanks.
