parameters of ENSURE-CLASS-USING-CLASS vs. AMOP

[Kalle Olavi Niemitalo]

In AMOP, the function ENSURE-CLASS-USING-CLASS is specified to
take the positional parameters CLASS and NAME and then a set of
keyword parameters.  In pcl/std-class.lisp however, the
positional parameters are in the opposite order: NAME and CLASS.
Is this difference intentional -- does the PCL of CMUCL follow a
published specification other than AMOP?
