- add -DPOSIX to pico build so that it doesn't use the sgtty cruft.
- clean freebsd-specific files too.
- correctly specify wait() as taking an int, rather than configuring it
for "union wait *" and adding patches to cast them to int's.
- use POSIX counterparts for pine proper (signals, non-blocking, termios)
- correct path to /usr/bin/passwd (not /bin/passwd)
- revert 3-char identifier to "BSF" not "BSI" (originally, BSN = NetBSD,
BSF=FreeBSD, BSI=BSDI)
- use more usual paths for news files. both cnews and inn* default to
/var/news (usually), and the inn ports default to
/usr/local/news/lib/active (cnews uses /usr/local/lib/news/active)
None of our ports use /usr/spool/news or /usr/lib/news/active.
