Yeah, I found some of your posts after I asked here
I personally really liked the idea of not having to think about libgcc and libstdc++, but I must say that I didn't think it through. You're absolutely right about the non-standard behaviour.
I saw that you recommended the "MinGW Builds" distributions and have a question about it (as I'm not very deep into different compilers yet
): Whats the difference to the "standard" MinGW suite from mingw.org? Its pretty confusing to read about different gcc Versions (mingw, tdm, mingw builds etc.) and still finding a "mingw" directory in every one of them.
