See below.

It is easier to run emacs.exe directly, like John suggested.  When GDB
shows its prompt, type "run" and press RET to start Emacs.

Wasn't that with Emacs 20.7?  I have no idea who compiled that and
how, but it's quite possible that those old versions were build with
the Microsoft compiler, not with GCC.

You will find the latest GDB compiled for Windows here:

Thanks.
