      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.
      31
