Uh, there's one problem here.  There are four definitions which are
non-POSIX:

  /* CYGWIN-specific values .. do not touch */
  #define _SC_NPROCESSORS_CONF              9
  #define _SC_NPROCESSORS_ONLN             10
  #define _SC_PHYS_PAGES                   11
  #define _SC_AVPHYS_PAGES                 12
  /* end of CYGWIN-specific values */

These have been added back in 2000, and they were never guarded with
an `#ifdef __CYGWIN__'.  All four values are supported by Linux, FWIW.
When I patched sys/unistd.h yesterday, I contemplated the idea to
guard them.  However, since they were *never guarded, I don't know
if they aren't actually supported by RTEMS.  That's why I left them
unguarded.  Is that ok with you?
