Pointer subtraction result is a long if int might not be big enough to
hold it.  A couple of bugs in beta-test Mg were related to this.  This
seems to be strictly an intel bug.  (I've also used C compilers where
pointer subtraction resulted in a 16 bit int -- but only 64k bytes of
memory were addressable.)
