Alex,

Do you have time to try to build libssh 0.6.3 like you did for 0.5.5?
If not, I'll try to do so over the next week or 2.

Like before, you need to incorporate the pageant patch:
http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=448
However, it does not apply cleanly. Many of the hunks fail. You are
much better at C programming than I am.

The 2 other patches (libssh-0.5.x-accept-forward.patch &
libssh-0.5.x-unblock.patch) have been upstreamed.
