- add a new INTPTR_IS_LONG define and use it. - XXX: the PTRDIFF, SIZEOF, INTPTR defines really make lint more relaxed in some platforms than others. We should really be looking for the particular tokens to enable this kind of checking. I.e. now: char *p; int foo = (int)p; does not produce a warning on INTPTR_IS_LONG == 0 platformas. In reality it should only elide the warning if: char *p; int foo = (intptr_t)p; but it is not that smart (yet).
