Here is an example for int_fast8_t: typedef signed char int_fast8_t; #define INT_FAST8_MIN INT8_MIN #define INT_FAST8_MAX INT8_MAX Now if int_fast8_t uses "int" as underlying type like this: typedef int int_fast8_t; which value is its MIN/MAX macros supposed to have? Is it allowed to use the same "char" limits as above or do I need to use #define INT_FAST8_MIN INT32_MIN #define INT_FAST8_MAX INT32_MAX in that case? So this is not about user code but an implementation question. Thank you, Gunther Nikl
