bug#17510: 24.3.91; Problem with `emacs --daemon' in cygw32 build

[Ken Brown]

This bug was reported in the Cygwin mailing list:

  https://cygwin.com/ml/cygwin/2014-05/msg00303.html

In a Cygwin terminal, do the following, where "emacs" denotes the cygw32
build of emacs (--with-w32).

1. $ emacs --daemon -Q
2. $ emacsclient -c
3. `C-x 5 0' in the client window to exit the frame.
4. Repeat steps 2 and 3.
5. Attempt to carry out steps 2 and 3 a third time.  The message 
"Waiting for Emacs..." appears in the terminal, but no new frame opens.

This problem is specific to the cygw32 build; it does not happen with 
the X11 build of emacs on Cygwin.  It also doesn't happen if the server 
is started via `M-x server-start' in an existing emacs.
