You will undoubtedly get a dozen messages saying this, but there
is a world of difference between assigning 0 to a pointer (or
testing a pointer against 0) and passing an (int)0 to a function
where a (whatever *)0 is required.  The latter is not only not
guaranteed to work, it is guaranteed NOT to work on machines with
different sizes for (int) and (whatever *).
