Hi Eli,

I didn't reply to your pings because I don't feel qualified to review changes related
to mingw (you are probably the most qualified person here, since you use it).  Given
the lack of response, I'd say you can go ahead with the change, tt seems relatively safe.

I have one question below.

Do we need "defined(__cplusplus)", since we are always building GDB as a C++ program?
