Oh, I know it's incorrect. It's also common enough that a compiler vendor
on a system where 0 doesn't have the same size and bit pattern as (void *)0
would be foolish to #define NULL as 0 in <stdio.h>.

Yes, it's better that everyone write correct code. But be liberal with
what you accept... after all, the person you're punishing with a B&D
definition of NULL is your customer.
