I'm not 100% sure about that.
static pointers may be required to be initialised to NULL.
If NULL isn't the 'all 0 bit pattern' then the memory would need
to be initialised to a different pattern.
Not that anyone is likely to implement such a system because far too
much code will break.

The only system I knew where 'native' NULL pointers were 'all 1s'
used 0 in its C compiler.
