Why do you need to do this?  i.e. what are you doing with breakpoints
that current versions of GDB don't handle for you?  (There may be a
good reason, I'm just curious what it is.)

It's just unimplemented.  However, you might want to try a current CVS
snapshot.  I think it should work now that Pedro switched win32 over
