I believe that

enum A { };
class C {
   enum A : int();
};

is a syntax error for attempting to declare an enumeration with an 
underlying function type, since the default rule in case of ambiguity is 
always to consider it a type-id. I do not believe that the patch 
correctly handles this; I think it should instead attempt to determine 
if it is a type-id before the semicolon/opening brace, and then act 
accordingly.
