Before making this comment, I looked at SunOS 4.x (based on 4.3, I
think) and FreeBSD 2.05, based on 4.4. Nowhere do these
Linux-specific flags occur. W.R. Stevens, in his discussions on
signals in BSD, does not mention these either.
Can you give me any actual evidence of these flags occurring in any
BSD variant?
