AFAIK, these are ISOC99 types and are supposed to be defined in stdint.h
and to be included into sources via stdint.h or inttypes.h (normally
implictly includes stdint.h).

Apparently, newlib is not ISOC99-ready. As a work-around, we could
either provide a stdint.h with RTEMS or try to get it properly
introduced into newlib.

Anyway, if the code your are trying to compile is expecting these typesm
in machine/types.h, it is bugged (machine/*.h should not be accessed
directly and is not standardized at all) or probably relies on a
BSD-proprietary feature.
