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.)
