[IIRC]  NULL is _always_ 0, as far as the C language is concerned.  At
the machine level, the null pointer could be something else, but you
don't see that far down.  Check the C FAQ to be certain.  In C++, this
is definitely true, since they recommend bare 0 instead of NULL.

And if '\0' (NUL) isn't always 0, we're all screwed ;-)
