Since it's a pretest it's not advertised there.
You can find it at http://alpha.gnu.org/gnu/emacs/pretest/

Ah, and indeed the code in the pretest won't help.
We need further changes to gdb-mi.el to accommodate your use case, but
those changes would be too intrusive to add at this stage, so it'll have
to wait for after 24.1.

In the mean time, I suggest you use M-x gud-gdb RET which uses the old
(Emacs-22) simpler GUD interaction and just requires a "--fullname"
argument (and whose absence won't be as problematic, tho it'll prevent
Emacs from jumping to the source code for you).
