Hi, I updated Cygwin today and hit the same problem, except even after
I added "-listen tcp" xterm (and gvim) still refused to work
complaining about "No protocol specified" (before was: "Can't open
display").

Putty logs say "Opening X11 forward connection succeeded" (before
"-listen tcp" it was: "Forwarded X11 connection terminated due to
local error"), which seems to indicate that the problem is with the X
server (and the way xterm/gvim communicate with it).

Ssh-ing to the server from Cygwin terminal works and I can even launch
gvim from the Putty's tty by specifying the same DISPLAY the Cygwin
connection provides.

After reverting to some early 2014 version of xinit and xorg (thank
god for Cygwin Time Machine) everything resumed working properly.

(on a side note, I tried to figure out what are the possible "-listen"
options by looking at the xserver code, there are three, "tcp",
"unix", "local". What does "local" mean, couldn't it be loopback
adapter? Where is "_XSERVTransNoListen" function implemented?)
