Probably the easiest way to figure this out is to write a function that
calls a method in C++, compile it with the -gl switch, and run OBJTOASM
on the output.

In general, arguments are pushed left-to-right, the 'this' pointer is
pushed last, and the callee cleans up the stack. To get the 'mangled'
name of the method to call, run OBJTOASM on the .OBJ file that contains the
definition of the method.
