The code makes no assumptions about the relative size of pointers and longs or ints (as far as I know).  Sometimes the difference between two pointers is stored in a type that may be smaller than a pointer, but only when it is known that it will fit.  The only assumption is that a long is at least 32 bits and that a short is at least 16 bits.
