--- Comment #20 from Paolo Carlini <paolo.carlini at oracle dot com> 2012-11-26 13:00:08 UTC --- Well, then we should double check whether it warns at all when bitfields are not involved, because I don't see anything bitfield-specific about the warning. Maybe it just warns less for these narrowing issues with scoped and unscoped enums?
