Code below fails to compile using mingw-g++4.7.1 from sourceforge.net/projects/mingwbuilds:

struct C{}; // enable ADL

void f(C){}

int main()

	std::thread t(std::bind(&::f, C())); //error
}

The line 191 of <thread>(in member template _M_make_routine):

return make_shared<_Impl<_Callable>>(std::forward<_Callable>(__f));

After I adding "std::" before "make_shared", it works fine.

Note: there is something wrong with the error message("unimplemented"). I'd file another bug for it.
