I can't reproduce this.  And I'm puzzled by the output:

On my system if emacsclient can't find the socket (which only happens if 
there's no server running), I see the following in a Cygwin Terminal 
(mintty):

$ emacsclient-w32 foo
emacsclient-w32: can't find socket; have you started the server?
To start the server in Emacs, type "M-x server-start".
emacsclient-w32: No socket or alternate editor.  Please use:

         --socket-name
         --server-file      (or environment variable EMACS_SERVER_FILE)
         --alternate-editor (or environment variable ALTERNATE_EDITOR)

I also don't understand why emacsclient would be trying to open 
/dev/cons0.  Do you by any chance have EMACS_SERVER_FILE set in your 
environment to /dev/cons0?

I can't reproduce this either.  I tried it in a fresh Cygwin install, 
just choosing emacs-w32 and its dependencies.  I ran 'emacs-w32&' in a 
Cygwin Terminal, emacs opened in a new window, and there was no problem 
after clicking on "About Emacs".
