     90 > I'm afraid it seems '-listen tcp' is not enough for PuTTY to successfully connect. 
     91 > If the server was started with -auth (which startxwin does since xinit-1.3.4-1), then PuTTY will need authorization data to successfully connect. 
     92 > Whilst you can do this by setting the "X authority file for local display" in PuTTY's configuration to the Windows path equivalent to ~/.serverauth.NNNN, this isn't much of a solution as this filename changes everytime the server is started. 
     93 > Perhaps xinit needs an option to avoid using -auth? One can demonstrate that works by starting the server directly, e.g. using 'XWin -multiwindow -listen tcp' rather than 'startxwin'.
