No problem, I was just a bit surprised because you did it "right" before I think...

I understand that you need to change the type of the function parameters, but if you also need to cast the function arguments where the function is called that would be such a gigantic compiler bug I can't imagine that is really the case.
Also at least for gcc you can just cast the variables in the constraints, but I think clang or lock have issues with that...
