That doesn't say how a 0 value for a pointer is represented; it's just how
it's written in the program text.
The compiler knows the types and can convert (same as double = 0).

In practice, you can't change it because too much code assumes that mallocz
and memset(..., 0, ...) of structures
containing pointer values will initialise them to null.
