It would be good to consolidate these. I'd suggest it comes in through
#include <rtems/inttypes.h>
without the _extensions bit is unnecessary if this is part of the
"RTEMS" headers.

I think there are some problems with _ in file names for some platforms?

Yes, and the rtems/inttypes.h should ideally pull in "Standard"
inttypes.h and then extends them.

This would be my preference.
