Actually, int64_t is optional (as even C18 and POSIX-2018 do not require it),
whereas ptrdiff_t has been required since C89. More importantly, int64_t would
be overkill on 32-bit GNU/Linux, whereas ptrdiff_t suffices and is typically
more efficient.

(Besides, what would we do if 72-bit pointers came back into vogue? :-)
