In the file Code/CLOS/class-finalization-support.lisp, in the
function compute-class-precedence-list-assuming-superclasses-finalized,
a simple error ("can't compute the class precedence list") is signaled.
To avoid the simple error, in the file Code/CLOS/conditions.lisp,
define a new condition named UNABLE-TO-COMPUTE-CLASS-PRECEDENCE-LIST
modeled after the other conditions in that file. Do not use the
:REPORT option. Define a slot %OFFENDING-CLASS with reader
OFFENDING-CLASS.
In the file Code/CLOS/condition-reporters-english.lisp, define
a method for reporting the new condition, modeled after the other
methods in this file.
