Marek Polacek <mpolacek at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |mpolacek at gcc dot gnu.org --- Comment #1 from Marek Polacek <mpolacek at gcc dot gnu.org> --- I don't see a bug; // -fallthrough warns because it doesn't match any of regexps in the manual for the level =3 (it has a space at the beginning). "//-fallthrough" doesn't warn.
