Using only the X server of Cygwin

[Jeremy Wilkins]

A while back I did some work creating a standalone XDMCP client, more as 
a test than anything.

Xwin depends on cygz.dll & cygwin1.dll as ago said. Xwin complains if it 
doesn't have rgb.txt, this can be put anywhere though and its location 
specified in the Xwin command line (needs a cygwin style path to the 
file though).

Xwin still needs a /tmp. If cygwin isnt installed properly, then / will 
default to the root of the drive Xwin is running from (normally c:).

It needs this folder for several reasons, it creates Xwin.log here, and 
a local socket .X11-unix (can be stopped passing '-nolisten local' to 
Xwin). It also needs /tmp if loading xkb keymaps.

/tmp can be mounted whereever you like using cygwins mount command, this 
will be remembered for when you then run Xwin (hence xkb's and Xwin.log 
can go where you like). Mount only depends on cygwin1.dll

fonts aren't required if you specify a font server using Xwin cmdline 
parameters.

I've found out most of this since I wrote my XDMCP client, but its 
available at http://www.jeremywilkins.freeserve.co.uk/eXtend/ warning 
this is a VB6 app so probably isn't gpl'd.

Hope this helps.
