Correct - those are [u]intptr_t, the exact sized types, and the types
(exact, fast, or least) with sizes other than 8, 16, 32, or 64. As a
good general rule, those optional types will be missing only if the
implementation doesn't support any integers of the specified size. What
would you want your code to do on an implementation that doesn't support
the size that you would otherwise specify?
