I think that was answered several times, but here it goes again: in
real life, long long is more widespread and better supported than
int64_t. (For instance, in my Linux, printf has a modifier for long long
[ll], but there is no modifier for int64_t.)

That is an error in the manual. That definition was not updated to
5.3. (Come on, that was a work version...) Forget the ptrdiff_t.
