  25 Oops, now why did you do that?
  26 O, never mind, just try it again with

  28 BSD4_2_OPEN = 1 or      for Berkeley 4.2, Ultrix etc.
  29 POSIX_OPEN = 1 or       for POSIX compliant systems.
  30 USG_OPEN = 0 and BSD4_2_OPEN = 0 and POSIX_OOPEN
  31         for Berkeley 4.1, v7 and whatever else
