A prebuilt version can only support one type of c++ lib. Did you mean we should provide two kinds of prebuilt libcocos2d that using two different c++ libs?

I don’t know if cocos2d can compile with c++_static or not. I don’t remember if there is a good reason to choose one instead of other one. But cocos2d-x uses gnustl_static from very early version, so we know it works well. You can replace it with c++_static if you like, but it is not fully tested.
