Actually, NULL should be defined as a plain '0'.  Comparison of
pointers against 0 is a special case in 'C' as is casing 0 to a
pointer.  Both should be the same.  In this context, the definition of
NULL doesn't matter.  It only matters when calling functions
w/old-school K&R prototypes or through "...".

I agree we should compare against NULL if the functionr returns a
pointer.
