Subject: [PATCH] _BSD_SOURCE for unistd.h, take 2

This is what was left from the comments.
This adds L_SET & co., and defines 5 functions that had been under
_GNU_SOURCE only, when _BSD_SOURCE is defined.
If I wanted to make things a little easier on those porting, I might
add something like this when _BSD_SOURCE is defined:
#warn "BSD setpgrp should be changed to setpgid"
That's not essential, though.
