Oops, now why did you do that?
O, never mind, just try it again with
USG_OPEN = 1 or         for System III, System V etc.
BSD4_2_OPEN = 1 or      for Berkeley 4.2, Ultrix etc.
POSIX_OPEN = 1 or       for POSIX compliant systems.
USG_OPEN = 0 and BSD4_2_OPEN = 0 and POSIX_OOPEN
        for Berkeley 4.1, v7 and whatever else
