  21    The intention of this file is to supply definitions that work with
  22    avr-gcc's -mint8 that sets int to an 8-bit type.
  23
  24    This file is intended to yield the same results as newlib-stdint.h,
  25    but there are some differences to newlib-stdint.h:
  26
  27    - AVR is an 8-bit architecture that cannot access 16-bit values
  28      atomically, this SIG_ATOMIC_TYPE is "char".
  29
  30    - For the same reason, [u]int_fast8_t is defined as 8-bit type.
