This prevents everyone one the server side machine to use privileged
ports, including the admin. But that's no problem anymore since I
updated the OpenSSH port on ftp.franken.de as announced yesterday.

I assume I missed the point here. There's only one port of
OpenSSH-2.1.1p4 to Cygwin and it's the one I put on ftp.franken.de.
I changed it yesterday to ignore the uid when trying to use an
explicit port and to fix a bug in scp. The last one is a more important
problem so I suggest using that 2.1.1p4-2 version, nevertheless.
BTW: It has the "open pid file in binmode" fix as well...
I still hope to get the portable OpenSSH maintainers to merge the
Cygwin port in their official build tree but as I mentioned in an
earlier posting they aren't that enthusiastic. I hope they aren't
convinced that "Windows sucks" is a valid argument as it's usual
in some other projects.

It works for each `normal' user on NT now since NT doesn't restrict
well known port access to a privileged sort of user. And it works
for each Cygwin uid now ;-)
