RE: [avr-gcc-list] AVR-GCC variable size

[Eric Weddington]

You can find out your answer by looking in the stdint.h file in
<install>\avr\include:


/** \name Fastest minimum-width integer types
   Integer types being usually fastest having at least the specified width
*/

...

typedef uint8_t uint_fast8_t; 


If you have it in your stdint.h file, then it's supported. ;-)
