#ifdef. No 2 C compilers ever seem to agree.
It's a major problem in C, hence bringing it up here. Even size_t is often
broken in C. I have worked on 64bit systems with 32bit pointers where
size_t was still 64bit, but ptrdiff_t was 32bit (I think PS3 is like this,
but maybe my memory fails me)
I want to be confident when I declare a numeric type that can interact with
pointers, and also when I want the native type.
