non us keyboards with cygwin, xfree86, Xwin -query XDMCP

[pbs]

Setup an out of the box cygwin installation with Xfree86
  bash-prompt$ uname -a
  CYGWIN_95-4.0 local_host 1.3.22(0.78/3/2) 2003-03-18 09:20 i586[snip]

Question Short version:
----------------------
With or without:
/etc/x11/XF86Config-4 installed with
    Option "XkbLayout"  "gb"
gives the error:
    Couldn't load XKB keymap, falling back to pre-XKB keymap
What do I have to do to get Xwin.exe to read the gb XKB keymap?

Question Long version:
----------------------
My cygwin bash pompt is configured for a "gb" keyboard
-- If I press the @ key I get an "@".

If I run the following command from a bash prompt
   Xwin.exe -emulate3buttons -query remote_host &

The log file "/tmp/XWinrl.log"  contains the following error:
   (==) Using preset keyboard for "English (United Kingdom)" (00000809), 
type "4"
   (EE) No primary keyboard configured
   (==) Using compiletime defaults for keyboard
   Rules = "xfree86" Model = "pc105" Layout = "gb" Variant = "(null)" 
Options = "(null)"
    Couldn't load XKB keymap, falling back to pre-XKB keymap

If I open an xterm and press the "@" key I get a double quote
key -- which is to be expected with the above error as it is what a
US key mapping gives.

I have gone throught archive and the previous thread which
came closes to answering my question was:
the post by Alexander Gottwald
   http://sources.redhat.com/ml/cygwin-xfree/2003-02/msg00185.html
with a URL to a minimal XF86Config
   http://www.tu-chemnitz.de/~goal/xfree/XF86Config.bz2

I have installed the file as /etc/x11/XF86Config-4 then uncommented
and modified the lines
   #  Option "XkbRules"   "xfree86"
   #  Option "XkbModel"   "pc105"
   #  Option "XkbLayout"  "de"
to
     Option "XkbRules"   "xfree86"
     Option "XkbModel"   "pc105"
     Option "XkbLayout"  "gb"

Now when I run:
   Xwin.exe -emulate3buttons -query remote_host &
The log file contains:
   [snip]
   (==) Using config file: "/etc/X11/XF86Config-4"
   [snip]
   (==) Using preset keyboard for "English (United Kingdom)" (00000809), 
type "4"
   (**) Using keyboard "Keyboard1" as primary keyboard
   (**) Option "XkbRules" "xfree86"
   (**) XKB: rules: "xfree86"
   (**) Option "XkbModel" "pc105"
   (**) XKB: model: "pc105"
   (**) Option "XkbLayout" "gb"
   (**) XKB: layout: "gb"
   Rules = "xfree86" Model = "pc105" Layout = "gb" Variant = "(null)" 
Options = "(null)"
   Couldn't load XKB keymap, falling back to pre-XKB keymap

What do I have to do to get Xwin.exe to read the gb XKB keymap?

BTW: Yes I know that I can run xmodmap as a client application. But
I would like to get the correct keyboard into the server without
doing this, so that the remote login clients(s) have access to the
correct key bindings.
