ANSI does not require a prototype for non-variardic functions (as far as I
can tell).  As a result, for a certain class of popular machines, under
certain compiler options, defining NULL as 0 will be incorrect, while
'(void*)0' is correct.

And the program that would core-dump on this would be perfectly correct,
according to ANSI.  The header file would, therefore, be wrong.
