From 25018aae1e7a8c2288f61c32416e8d3c083a479f Mon Sep 17 00:00:00 2001

Subject: Define NULL to be __null for C++: better quality of implementation.
 __null is a magic constant of integral type that converts to a null pointer
 as should be, but warns for ambiguity when used to resolved an overload
 between an integral type and a pointer type.
