/*
The intention of this file is to supply definitions that work with
avr-gcc's -mint8 that sets int to an 8-bit type.
This file is intended to yield the same results as newlib-stdint.h,
but there are some differences to newlib-stdint.h:
- AVR is an 8-bit architecture that cannot access 16-bit values
atomically, this SIG_ATOMIC_TYPE is "char".
- For the same reason, [u]int_fast8_t is defined as 8-bit type.
