If you don't declare the argument types properly, your code will not be
strictly conforming.  The only "cheat" that is allowed is to use char*
instead of void*, because the standard required these to have the same
representation.  This is NOT required for other pointer types, just for
these two.

The three obvious solutions are:
	explicit cast on each usage of the arguments
	use a macro to encapsulate the above casting
	use auto variables of the appropriate type
