If the compiler were to recognize the number following the `int' as
the number of bits to be used then one could specify whatever they
wished.  This would lend itself to `no problem' when porting assuming
the compiler could recognize this format.

BTW, IMHO, short should be the sizeof(int)/2 and long should be
sizeof(int)*2.
