I have basically got a XDM client up with nothing but cygwin1.dll,
cygz.dll and XWin.exe. 

I have used a font server as suggested.  The dos command is nothing more
than:
C:\FreeXWin\XWin.exe -screen 0 800x600x16 -broadcast -fp
tcp/192.168.0.2:7100

This works fine on a system that has had cygwin installed and then
removed, provided I leave c:\cygwin\tmp as an empty directory. 
Presumably it gets this location from the windows registry from the
initial installation of cygwin.

How does one tell the cygwin dll what directory to use for tmp if cygwin
has never actually been installed?  (ie, preferably from a batch file /
environment variable etc)  Or am I required to do a minimal cygwin
install?

Cheers,
