Because you're looking at the generic OpenSSH README, whereas you should
be looking at the platform-specific (Cygwin) one.  "cygcheck -l openssh |
grep README" shows that there is one in /usr/share/doc/Cygwin -- that's
the one you ought to have used.

-> /usr/share/doc/Cygwin/openssh.README .

This is arguably a packaging bug.  Corinna, care to patch the official
README to point to the Cygwin-specific one (or simply add an INSTALL file
that points to it?).

That's because the documentation is for stock OpenSSH, and has no
Cygwin-specific parts.

Yes, but not by hand.

Did you try running it? :-)  Seriously, with a --help option?

Yes.  X forwarding works just fine.

Yes.  I use a shortcut to the following batch file with RealVNC:

@echo off
cd C:\Program Files\RealVNC
vncviewer.exe | c:\cygwin\bin\ssh -L 5900:127.0.0.1:5901 %1 cat

and select "localhost:0" as the VNC server.  The pipe (and the "cat"
command) are needed to make sure that ssh waits for vncviewer to exit.
