+   OSX provides a getlastlogxbyname function that automates the reading of

+   is wrong for both releases so I just removed it, together with the
+   unnecessary (Cygwin 1.5.x) or wrong (Cygwin 1.7.x) default setting.

+     Add support for an experimental zero-knowledge password authentication

+     "Password Authenticated Key Exchange by Juggling", 16th Workshop on
+     Security Protocols, Cambridge, April 2008.
+     
+     This method allows password-based authentication without exposing
+     the password to the server. Instead, the client and server exchange
+     cryptographic proofs to demonstrate of knowledge of the password while
+     revealing nothing useful to an attacker or compromised endpoint.
+     
+     This is experimental, work-in-progress code and is presently
+     compiled-time disabled (turn on -DJPAKE in Makefile.inc).

-   session starts (ie when a pty is allocated) but this means that accounts
-   that have primarily non-interactive sessions (eg scp's) may gradually
-   accumulate enough failures to lock out an account.  This change may have
-   a side effect of creating two audit records, one with a tty of "ssh"
-   corresponding to the authentication and one with the allocated pty per
-   interactive session.

-     initial channel code bits by markus@. This is a simple and easy way to
-     use OpenSSH for ad hoc virtual private network connections, e.g.
-     administrative tunnels or secure wireless access. It's based on a new
-     ssh channel and works similar to the existing TCP forwarding support,
-     except that it depends on the tun(4) network interface on both ends of
-     the connection for layer 2 or layer 3 tunneling. This diff also adds
