20001202
- (bal) Backed out of part of Alain St-Denis' loginrec.c patch.
- (bal) Irix need some sort of mansubdir, patch by Michael Stone
- Replacement for setproctitle() - HP/UX support only currently
- Improve PAM support (a pam_lastlog module will cause sshd to exit)
+ and maybe support alternate forms of authenications like OPIE via
+ pam?
- Complete Tru64 SIA support
