Do I need a life?  I'll sort those out this weekend (and resist the 
temptation to pick at another loose thread) and get them into current GDB.

This will mean that the pressure is on to quickly spin out a GDB 5.4 
containing the updates.

Nick,

These patches, among other things, add the new CLI command 
`interpreter'.  This command lets you do things like:

(gdb) interpreter mi -<mi-command> <mi-args>
.... mi output ...
(gdb)

and will allow EMACS to query GDB using the MI (breakpoint list, frame 
backtrace, ...) with out requiring a complete rewrite.

Assuming that the level-two annotations are largely needed for the CLI 
version of those, this in turn will make it possible for EMACS to 
migrate at least partially to MI and at the same time drop the only just 
added level-two annotations requirement.

Long term, it would be good if EMACS used the -mi interpreter by 
default, but I don't see that as an absolute requirement.

RMS has indicated that if I and you agree to finish the MI support that 
Emacs needs, and convert Emacs to use it, in a short time (say, three 
months), he would go along with that plan.

I do manage to cover the MI side this weekend, can you, with some help 
from a few other GDB / EMACS hackers, cover the EMACS side?
