class-all-default-initargs #:slot-unbound

[kanderso@WILMA.BBN.COM]

The classes at the top of the metabraid seem to have their
class-all-default-initargs unbound, although it seems like they should
be ().  THis causes mki to fail.  Here's a patch but i don't know what
the correct solution is:

(setf (class-all-default-initargs (symbol-class 't)) ())
(setf (class-all-default-initargs (symbol-class 'standard-class)) ())
(setf (class-all-default-initargs (symbol-class 'class)) ())
(setf (class-all-default-initargs (symbol-class 'standard-slot-description)) ())
