sbcl method-combination rewrite

[csrhodes]

Hi,

My method-combination rewrite has, unfortunately, broken quid-pro-quo. It's (presumably) a similar issue to that already affecting Lispworks, Allegro and CLISP: the defguarantee on make-instance at the end of metaclass.lisp tries to change the method combination of make-instance, which is not supported in my rewrite.

We could talk about whether it should be! But given that existing practice is against you, please could you #-sbcl out that defguarantee for now?

Thanks,

Christophe
