The warnings aren't because of your DX, it happens no matter what. I don't know what the problem there is. I get it
when linking static A4 too. It's safe to ignore them though. But needing to link in libstdc++ is a bit odd... that
could be something to do with your mingw setup, since I've never seen that or heard of anyone else seeing it. It
wouldn't hurt I suppose to explicitly link it, but I'm wondering if there isn't something else at fault. What version
of gcc/g++ do you have? What packages did you install?
