Hmm. I'm very aware that gdba doesn't auto-display complex data structures
(arrays of structures or structures with arrays in) and plan to solve that
when I can find the stamina. If you are more specific about other problems
then I will try to solve them.

That will restore the toolbar but it will also kill any buffer whose name
starts with `*'. I could replace:

        (if (eq gud-minor-mode 'gdba)
with    (if (memq gud-minor-mode '(gdb gdba))

which would do what you want. However, I wrote gdb-quit for gdba and
I've not analysed what other consequences that might have.

In my opinion, M-x gdb is quite limited. I'm guessing, but I bet most
people on this list use gdb from the command line when they debug emacs.
It has quite some nifty features that make it easier to use: completion
of GDB command names, completion of user-defined procedure names, <RET>
sometimes repeats the previous command (handy for stepping through the
program or looking at a listing), readline interface etc, etc...
