Comment (by nick.withers):

 New patch attached, tested with:
   - MVME3100 BSP and my code, which "seems to work" - it doesn't itself
 use ''in_8()'' or ''out_8()'', though. For what it's worth, I've actually
 had my ''io.h'' (and just it) patched with the fixed-width types since the
 ticket was opened
   - ''gmake all'' (configured with ''--enable-rtemsbsp="mvme3100 mvme5500
 beatnik" --enable-tests=yes''), redirecting stdout and stderr and
 comparing before and after - there are no new warnings

 Couple of notes:
   - I'm not ''totally'' sure that passing in a variable of less width than
 a CPU register to an asm statement is kosher, e.g.:
 -       int ret;
 +       uint8_t ret;

         __asm__ __volatile__("lbz%U1%X1 %0,%1; eieio" : "=r" (ret) : "m"
         return ret;
   - I only added the stdint.h header (or inttypes.h if the PRIx macros
 were used) to files which didn't already use the C99 fixed-width types.
 Those that were already missing it still are
