Actually, the C reference manual calls for up to *three* lengths of integers:
"short int", "int", and "long int"; any of them may be equivalent to the
other as long as sizeof(short int) <= sizeof(int) <= sizeof(long int).
In practice, it may cause problems if "int" isn't the same as any of the other
two, but that's because of historical practice, not because of the
"specification" of the language.
