--- Comment #2 from Florian Weimer <fw at gcc dot gnu.org> --- (In reply to Marek Polacek from comment #1) > Why would it have to be error? If you want errors instead of warnings, use > -pedantic-errors. I did not know about -pedantic-errors. It is extremely surprising that -std=c11 does not enable all diagnostics required by C11.
