MACL 2.0 final defines the pattern :record as a handle.
It used to (and I believe should be) defined as a pointer.
This will work...

    (defvar *grid-x-pattern* (make-record (:pattern :storage :pointer)
                                      (:array 0) 255
                                      (:array 1) 0
                                      (:array 2) 0
                                      (:array 3) 0
                                      (:array 4) 255
                                      (:array 5) 0
                                      (:array 6) 0
                                      (:array 7) 0
                                      ))

Won't work under 2.0 final definition of :pattern
