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
