define-method-combination examples

[sandra%defun@cs.utah.edu (Sandra J Loosemore)]

I have been trying to figure out how the long form of
DEFINE-METHOD-COMBINATION works.  The examples in the spec use a
function called MAKE-METHOD, which does not seem to be defined
anywhere.  Was this an oversight?  Can somebody supply a definition
for this function, or rewritten examples that don't rely on it?
