[g++ mingw eclipse] How do I setup Eclipse to use MinGw's g++ compiler?

[Sam Smith]

I've just downloaded and installed Eclipse and the C++ plugin (CDT).
The editor looks really good!
However, I do not know how I should integrate my MinGw g++ compiler with
Eclipse. I hope that someone on this list has already setup this environment
and is also willing to share the knowledge!

Thanks in advance!
