Wait, the command 'gcc' on macOS actually runs Clang? That's cold. How do you
think Apple would feel if we called Emacs "iPhone"?
Anyway, we can pacify Clang by disabling its -Wnull-pointer-arithmetic option,
so I installed the attached. I'd rather do this than go back to the old intptr_t
way of doing things, which has too many problems with missing type-checking at
the C language level (unless you configure with --enable-check-lisp-object-type,
which has its own set of problems).
