I would like to cast an int screen = 0; as a pointer (yes, with value zero)
so I can pass this as an argument to an assembly routine that alternativly
writes to a buffer or video ram depending on whether the passed parameter is
zero or a valid pointer to my buffer array.  This will work most of the time,
but when the argument is passed to functions that are members of classes the
warning becomes an error.

I know I could get this job done with more than one function (overloading),
but humor me on this one please.  I think I've missed a simple point in my
learning.
