On FreeBSD the <sys/types.h> defines the following types:

int8_t
int16_t
int32_t
int64_t
uint8_t
uint16_t
uint32_t
uint64_t
intptr_t
uintptr_t

These types are defined in <sys/_stdint.h> on FreeBSD.

On glibc only the following types are available via <sys/types.h>:

int8_t
int16_t
int32_t
int64_t

I would like to use the FreeBSD approach also for Newlib. Any objections?
