But if I run xhost in that session I will be setting xhost permissions
on the Linux Slackware system which is most definitely not what is
required.

It seems very odd that xhost requires access to the local display in
order to work as you need xhost to set permission to acces the local
display - sort of catch 22.

If I open just a cygwin terminal window on my Win2k system I simply
can't run xhost at all.

E.G.:-

    $ xhost
    xhost: Unable to open display ""

    $ export DISPLAY=192.168.13.25:0.0
    $ xhost
    Xlib: connection to 192.168.13.25:0.0 refused by server
    Xlib: no protocol specified

    xhost: Unable to open display 192.168.13.25:0.0

So how can one ever run xhost (and thus xwinclip)?

Maybe my win2k set up is wonly but 127.0.0.1 won't work for me, the
actual IP address of 192.168.13.25 does work though.  However a second
try seems to be OK, maybe I'd got into a mess before.  The 'catch 22'
above still applies though.
