[Matlab-emacs-discuss] How can I get emacs to display a stop-sign icon when I set a breakpoint?

[Dan B. <db...@gm...>]

(I also posted this question on Stackoverflow, so feel free to answer
there if you like)

I'm running emacs 23.4 on OSX, obtained from emacsformacosx.com. I'm
writing matlab code, using the latest code from
matlab-emacs.sourceforge.net.

I can set breakpoints and step through matlab code with no problems.
However, when I set breakpoints, no "stop-sign" icon appears next to
the lines that have breakpoints. The arrow icon indicating the line on
which you are stopped *does* appear.

I've seen emacs screenshots online that show stop-sign icons, but I
can't find any GUD documentation on this.

How can I get these icons to appear? Is this a problem with
matlab-mode, or something in my setup?

Thanks,

Dan
