That's not quite what the standard says.  It says (3.5.2.2) that
the enum identifiers have type int, but that
    "Each enumerated type shall be compatible with an integer type;
     the choice of type is implementation-defined."

So given:
	enum color { red, yellow, blue };
The constants red, yellow, and blue each have type int, but you
cannot predict the value of sizeof(enum color).  It could be
anything from sizeof(char) to sizeof(long).
