The test Wmissing-return2.c only has one of the two warnings. But as per "-Wreturn-type => Run both", and for backwards compatibility with the existing definition of -Wreturn-type, both warnings should appear for this test. (It's simply that only a subset of -Wreturn-type seems suitable to enable by default for C. Maybe the default subset, -Wreturn-type -Wno-missing-return (which is a combination that should also be included in the testcases), should have its own option name, although I don't know what that would be.) -- Joseph S.
