Yes. MI is under development too, that's why I included gdb-mi.el in GDB
- to keep up with the changes.

Emacs 22 still hasn't officially been released although you may have got
a pretest tarball, or possibly a snapshot packaged for a ditribution such

Probably just your gdb as your emacs is much more recent.

OK, well current gdb-mi.el says it's developmental.

Emacs 22 should be released shortly. You can get prebuilt binaries
e.g http://ourcomments.org/Emacs/EmacsW32.html (I guess by `make his own'
you just mean `build' - this shouldn't be too hard from the CVS repository

Sorry, without a more recent version of gdb you're pretty much on your own.
FSF GDB can do this:
* GDB can now be configured as a cross-debugger targeting native Windows
(mingw32) or Cygwin. It can communicate with a remote debugging stub
running on a Windows system over TCP/IP to debug Windows programs.
Maybe that does all you need.
