I'm not aware of any problems with __null.  If anyone has any overloading
bugs involving __null, please send them in.  There were certainly problems
with making (void*)0 magic in general, which is why I replaced that with
__null.

I believe that NULL should be retrieved from stddef.h, as I outlined
earlier.  This will get the __null definition, which should work for
everyone.  Does anyone have any practical problems with this?
