UseLogin portability

[Wayne Davison]

Back on April 4th I sent a patch that makes UseLogin work on Solaris.
This change also made UseLogin work with Unicos (both of which require
a valid utmpx entry before /usr/bin/login will run).  I have not heard
back from any of the ssh developers about this issue, and the current
snapshot doesn't appear to deal with this problem at all.

So, is there some issue here we still need to deal with?  Or was this
change simply missed somehow?
