INPUTS
cl
Class, which dispatcher is to be called.
obj
The object, on which the method is to be performed on.
message
The message. The first field is the same for all methods and specifies which method is to be invokes (see <intuition/classusr.h>).

The macros AROS_SLOWSTACKTAGS and AROS_SLOWSTACKMETHODS now use
AROS_TAGRETURNTYPE and AROS_METHODRETURNTYPE to create a variable
called retval in which the use suplied part of the function must store
the return value. If these types are not defined, then the types
default to IPTR.
