	C is way too permissive with `!=`, `==` and `if(var)` checks, which can mean too many things depending on what we compare. We force here a semantic NULL check for pointers types that will fail for anything else than pointers, and make the code more explicit about what is checked. This will fail at compile time on function pointers and anything that is not a pointer.
