If you fix the filename part of the --fullname status output string, 
that should at least make emacs able to track the current line for now, 
which is better than nothing.

Sinking a bunch of time into emulating --annotate output is probably a 
bad idea though, since emacs, the gdb team, and the rest of the world 
are moving away from it.

I don't know why M-x gdbmi wasn't working for me (with the real gdb 6.2) 
but I suspect that'll get fixed eventually).
