If that had been the case, there would have been little point having
separate short and long types. The general idea is that int gives you
the most efficient type for your system, and that short may be smaller
than that and long may be larger than that, as long as short is at
least 16 bits and long is at least 32 bits. Relying on the size of int
being portable has been a problem in several projects I've
encountered.
