Typedef names beginning with int or uint and ending with _t are potentially
reserved identifiers and may be added to the types defined in the <stdint.h>
header.  Macro names beginning with INT or UINT and ending with _MAX, _MIN,
_WIDTH, or _C are potentially reserved identifiers and may
be added to the macros defined in the <stdint.h> header.

It would be better if it had been explained that these statements
are not currently among the requirements given by the C standard,
but only advisories listed in the "Future Directions" section.
Names like uint64_t are not reserved, even in the not-yet-ratified
draft C standard.
