Hi

We are looking at adding RUSAGE_THREAD support to RTEMS. It is not in POSIX
but supported by Linux and FreeBSD.  Linux has it behind a __USE_GNU
guard.  FreeBSD does not have it behind a guard. This is what I propose to
add to sys/resource.h.

+#if __GNU_VISIBLE
+#define RUSAGE_THREAD   1
+#endif

Cygwin has its own version of the resource.h file so no impact.

Is this the appropriate guard set?

Thanks.
