3 It nearly conforms to C99 and to ISO/IEC TS 18661-1:2014.
4 Assumes typical host with 8-bit bytes, two's complement
5 representation, and no padding or trap representations, with int
6 widths equal to 8, 16, 32, and 64 bits. {uint,int}_fast{8,16,32,64}_t
7 may not correspond to the fastest types available on the system.
8 Macros are used instead of typedefs.
