Does the C front end warn about this mismatch?
I just tried the first test of g++.old-deja/g++.other/cond5.C and the C
front-end does *not* warn neither by default, neither with -Wall.
Do we warn about mismatch in comparisons?
Comparisons are dealt with separately, we have -Wenum-compare:
It seems to me that these should be covered by the same flag. Maybe
just add the warning to -Wenum-compare to start with; this isn't exactly
comparison, but it's another case of the usual arithmetic conversions
bringing them to a common type. For 4.8 I think we also want to improve
our handling of use of enums within their enum-specifier.
