In the synopsis, some types are identified as optional: int8_t, int16_t, and so on, consistently with C99, indeed.
On the other hand, intptr_t and uintptr_t, are not marked as such and probably should, consistently with C99, 18.104.22.168.
Change 17.4.2 [cstdint.syn]:
... typedef signed integer type intptr_t; ... typedef unsigned integer type uintptr_t; ...
Recommend NAD and fix as editorial with the proposed resolution.
