Interesting.  This gets me into a graphical mode where I have a source
window with a pointer in the fringe by the execution point. However, I
still don't have the other debugger windows (stack etc.), and I don't have
the little red dot in the fringe by breakpoints.

This gives the same as gdb --fullname

(gud-gdb-command-name "gdb 

If I try --annotate=2 I get all the debug windows, but now the gdb command
line usually won't do anything (eg if I type "list" nothing happens)! I did
however get a working system the first time I tried --annotate=2, with the
little red dot etc., but no joy since then

Thanks for your help so far. Any further thoughts welcome.
