  Tsk, tsk, tsk. This statment is true if sizeof(int) == sizeof(pointer).
Not a good assumption to make, eh? I do a great deal of programming using
Microsoft C 5.0 on IBM PEE CEE's. In large model, pointers are four bytes
long. However, constant integer expessions are ints, and an int is only two
bytes long.
