Oops, you're right. Then the situation must be the same as in 
C++? If enum ABC is by itself a parameter of a function, the 
argument will be int (and if it weren't, it would be promoted to 
int anyway), but if the enum is a part of a structure, then it 
can be anything...
At least, if enumerators themselves are ints, the enum type 
probably won't be larger than an int... small consolation :)
