Well, technically, adding "-nounixkill" to the XWin.exe parameter list
should do it, but it doesn't work for me.  When I open an XWin session on
a Win2k SP3 machine, Ctrl-Alt-Backspace still happily kills the server,
even with -nounixkill.  The command I used to start the X server was

XWin :1.0 -nounixkill

(since I have Exceed running on display :0.0) and pressed
Ctrl-Alt-Backspace in the window once the screen appeared to have
initialized (after a minute or so).  /tmp/XWin.log is attached, and the
versions of the relevant (IMO) installed software are below.  Please let
me know what further information I can provide (or experiments I could
try) to help diagnose the problem.
