Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Priority|P3 |P1 --- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> --- It's kind-of an ABI related warning so maybe use -Wabi? Or invent a new flag, -Wignored-attributes (as opposed to -Wattributes which is about "inappropriate" attributes).
