The following packages have been updated in the Cygwin distribution as 
test releases:

*** emacs-24.3.93-3
*** emacs-X11-24.3.93-3
*** emacs-w32-24.3.93-3
*** emacs-el-24.3.93-3

Emacs is a powerful, customizable, self-documenting, modeless text 
editor.  Emacs contains special code editing features, a scripting 
language (elisp), and the capability to read mail, news, and more 
without leaving the editor.

This is a pretest of the upcoming emacs-24.4, patched to make emacs use 
Cygwin's malloc instead of the one provided by emacs.  See


for details.

This patch has been applied upstream in the emacs development trunk but 
not in the emacs-24 branch, so it will not be included in the official 
release of emacs-24.4.  Nevertheless, I would like to include it in the 
emacs-24.4 package for Cygwin if it gets enough testing to convince me 
that it's reliable.  Emacs users are strongly encouraged to test it and 
report any problems.

1. The emacs, emacs-w32, and emacs-X11 packages each provide an emacs 
binary.  These are emacs-nox.exe, emacs-w32.exe, and emacs-X11.exe, 
respectively, in order of increasing priority.  The postinstall scripts 
use the `alternatives' system to create a symlink /usr/bin/emacs that 
resolves to the highest-priority binary that you have installed.  Thus 
the command `emacs' will start emacs-X11.exe if you've installed the 
emacs-X11 package; otherwise, it will start emacs-w32.exe if you've 
installed emacs-w32; otherwise, it will start emacs-nox.exe.  Similar 
remarks apply to emacsclient.

If you have installed both emacs-w32 and emacs-X11 and prefer to give 
higher priority to emacs-w32, run the script


You can later restore emacs-X11 as the default by running


2. Install emacs-X11 if you want to use the X11 GUI.  You can then type 
`emacs&' in an xterm window, and emacs will start in a new window.

3. Install emacs-w32 if you want to use the native Windows GUI instead 
of X11.

4. If you have sshd running and want to be able to run emacs-X11 from a 
remote machine, you need to enable X11 forwarding by adding the 
following line to /etc/sshd_config:

   X11Forwarding yes

You might also need to have the cygserver service running.

5. The script /usr/bin/make-emacs-shortcut can be used to create a 
shortcut for starting emacs.  See /usr/share/doc/emacs/README.Cygwin for
