We don't need to give up what we have in order to try something else
additionally, do we?

I think m3gdb works quite well on some platforms these days. Unfortunately,
it doesn't build on others.

On Windows we'll need something for the native debuggers anyway.

Improving the use of other C debuggers will be good, too, for platforms
we haven't got anything else.

What I've learned from this discussion is that we should definitely try
to support dwarf debugging format for the gcc backend. I'll add that
as a task for the 5.9 release.

And Jay has already announced that he will be working on a C backend.
That should open up other possibilities.
