No, no. TeXnicCenter already *does* use DDE - at least in the current
version (and it works like a charm). Read the FAQ (and help pages
pointed to):

This:

Should do all (or most) of what you need.

This results in both message and help-echo displaying the same thing
in the mode-line. It would be better to use format rather than
message.

I recall some bugs were fixed in the MS-Windows code to prevent
excessive redisplaying of help-echo in the minibuffer which was causing
CPU usage to approach 100% in some cases. Perhaps the fix went too far.

For a different approach to avoiding portability-related warnings from the byte
compiler, look at my `emacs-vers.el' package:

  <http://www.cs.utah.edu/~eeide/emacs/emacs-vers.el.gz>

With `emacs-vers.el', one can specify that Emacs flavor/version tests should be
resolved at compile-time by the byte compiler.  The optimizer can then
eliminate dead code (i.e., for the non-targeted versions of Emacs) that would
otherwise give rise to various warnings about undefined symbols, etc.

(Note that compile-time version testing is *not* the default behavior of the
`emacs-vers.el' package.  Comments in the file describe how one chooses between
run-time and compile-time version tests.)

Of course, compile-time version determination is not always what one wants.
For cases in which one wants run-time tests, `silcomp.el' looks like a nice way
to avoid unwanted warnings.

Eric.

Hello,

I'm using Mac OS 10.2.2 and the Emacs that came with it (21.1) in tcsh 
in the Terminal application. I'm attempting to use syntax coloring, 
with limited success.

I have this:

(global-font-lock-mode t)
(setq font-lock-maximum-decoration t)
(set-background-color "Black")
(set-foreground-color "White")
(set-cursor-color "White")
(custom-set-faces
'(font-lock-comment-face ((((class color) (background dark)) 
(:foreground "yellow"))))
...

in my .emacs file, and I've set my TERM environment variable to 
"xterm-color". Now I'm getting color, but the only colors available 
seem to be Red, Green, Blue, Cyan, Magenta, Yellow, Black, and White. A 
call to list-colors-display confirms this. Does anyone have any advice 
on how to get more colors (without switching to XEmacs)?

Thanks,
Matt
