Eli responded with "use MinGW GDB". I use a variation of that from
AdaCore; it works quite well.

Another solution is to use Cygwin X Windows and Cygwin Emacs. I
recently tried that for a different reason, and it works quite well.

If your C++ compiler is also Cygwin, that would give a single
integrated environment.
