Using Emacs built from the CVS repository, if you type `M-x gdba' you will get
a mode for GDB that has some of these features and more. Breakpoints are
displayed as red bullets in the display margin om a graphics terminal. They
are updated automatically even when set or deleted from the GUD buffer. This
mode (in gdb-ui.el) has other features: stack buffer, stream separation,
locals buffer, display windows etc. Please note, though, that it won't work
properly with a released version of Emacs so you can't just download the lisp
package.
