It could be as simple as: * c-c++-common/pr65403-1.c: New test. * c-c++-common/pr65403-2.c: New test. No inherent problems with the test, though I think we need to verify they still do the right thing given the hints the compiler will try to emit on unknown options now. That's easy enough to do once we have concluded on what the behvior should be now that the compiler emits hints for unknown options. Jeff
