Unable to connect to font server

I am trying to use an element of the form "tcp/" in my
font path, and it is being rejected. Furthermore, my testing shows that
XWin is not even attempting to open a socket. Is the "tcp" transport
still supported in the font path? Question 7.7 of the FAQ refers to this
syntax, so presumably it worked at some stage.

The font server I actually wish to use is on a remote machine, but I
have reduced it to a failing test case using localhost:

# Listen for connections on port 7100, in the background
$ socat TCP-LISTEN:7100 stdio >/dev/null &
$ jobs
[1]+  Running                 socat TCP-LISTEN:7100 stdio > /dev/null &

$ startxwin /usr/bin/true -- -fp tcp/

Welcome to the XWin X Server
Vendor: The Cygwin/X Project
[dix] Could not init font path element tcp/, removing from

# The background process is still waiting for a connection on port 7100
$ jobs
[1]+  Running                 socat TCP-LISTEN:7100 stdio > /dev/null &

# But if we make a connection to the port, then the listening process
will stop:
$ socat stdio TCP-CONNECT: </dev/null

[1]+  Stopped                 socat TCP-LISTEN:7100 stdio > /dev/null

# Conclusion: XWin never even made a connection to port 7100.

I have tested this on two machines, both running Window XP Professional
SP3. The difference is that on one machine Cygwin runs under a non-admin
account, and on the other machine the account has local admin rights. I
got the same results on both.

I've also tested this with Xming, and it does work.

Any idea what's going on?

Kind regards,
