I can see why one might want to allow the trailing comma, but what good is an
enum with no values?  I think this is almost in the same category as
zero-sized objects.  (I.e., the rule that allows small-valued enums to be
stored in a char could be logically extended to allow non-valued enums to be
stored in a zero-size type.)
