Personally, I never use NULL.  NULL is a misnomer.  Zero is defined
to be the invalid pointer, zero should be used.

But we've been through this before.  Assigning a type to NULL opens
up as many problems as it solves.  There are a class of machines where
byte pointers themselves are different than pointers to any other type.

If you are going to assing a type to NULL you probably ought to use
(void *).
