--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to David Krauss from comment #2) > Currently, enum promotions are incompatible between C and C++ modes. Does that matter? > Furthermore, when C++ requires promotion to signed int but the underlying > type is unsigned int, integer overflow may occur. How? If there are values of the enumeration that would overflow a signed int then it won't be promoted to a signed int. > I think this adds up to a bug and the C++ behavior should get its own bullet > at the end of that manual page. Saying what? The only issue I see here is that EDG chooses int where GCC and Clang choose unsigned int, even in the --g++ mode, but that's not a GCC bug.
