How's that?

The reason it's an issue is because of "fixincludes" fixing perfectly
reasonable headers by liberally inserting #ifdef __GNUC__. (I guess
they feel that since certain identifiers are "reserved for the
implementation", that means they're reserved for themselves.) I'm
confident that once gcc-3.3.1 is imported, #ifdef __GNUC__ will only
protect use of gcc special features, and not essential parts of the
implementation, so occasional use of naked "cpp" won't hurt anything.
