C11 7.18.1.1 says "if an implementation provides integer types with 
widths of 8, 16, 32, or 64 bits, no padding bits, and (for the signed 
types) that have a two’s complement representation, it shall define the 
corresponding typedef names." There are similar requirements in later C 
versions, and in C2x (which requires two's complement) this has been 
strengthened to "If an implementation provides standard or extended 
integer types with a particular width and no padding bits, it shall 
define the corresponding typedef names."

So the implementations you're thinking of must support the usual intN_types.
