This change breaks things for Emacs (I have this strange feeling of deja
vu...).

Did your stress tests include running Gdb on a dumb terminal?

I haven't the faintest idea what the problem is and everything seems fine on
an xterm:

^Z^Zpre-prompt
(gdb) 
^Z^Zprompt

but if I do the same from within Emacs, the annotations don't appear.

If you've not got Emacs 22.1, you can see it in an earlier version by doing
M-x shell and "gdb -ann=3" in the *shell* buffer.
