Hmm it turns out my compiler is d.r.t as far as it is concerned:

  # 34 "/usr/lib/gcc/arm-none-eabi/5.4.1/include/stdint-gcc.h" 3 4
  typedef signed char int8_t;


  typedef short int int16_t;


  typedef long int int32_t;


  typedef long long int int64_t;


  typedef unsigned char uint8_t;


  typedef short unsigned int uint16_t;


  typedef long unsigned int uint32_t;
