For DJGPP, yes, although there was a time when NULL was defined to be
__null sometimes (before they got that mess straightened out) and I've
encountered platforms where NULL is defined to something too strict to
be used as a generic null pointer.  Sad, but true.  The literal '0' is
always able to be cast to a pointer of any type, but that cannot
always be said for NULL (except most of the time in DJGPP, of course ;).
