Type safety in GM2?

I found I can't substitute C typed pointer which I don't know how to translate to GM2 with ADDRESS. But the problem arise that when I declare them as ADDRESS I could pass anything to them and the compiler doesn't complain but the resulted program will crash.

e.g: the library assumes the passed type to be a structure typedef-ed with void pointer that I don't know how to translate to GM2 so I substitute it with ADDRESS, but I found I could pass an INTEGER pointer to it without any complains from the compiler but my program would crash.

How to at least tell the compiler to check if the correct type was passed or is it impossible without a properly translated type to GM2?

I found the developers also used this trick heavily. Check ncurses.def and you will see they also substitute pointer to not translated structure with ADDRESS.
