Hmm... There must be some difference - on CMUCL, MAXIMA::INTERSECTION
breaks DEFPACKAGE. I discovered this as I converted
maxima-package.lisp to use DEFPACKAGE. First time loading the
DEFPACKAGE form works fine, second time (after loading the rest of
Maxima) it complains about the number of arguments to INTERSECTION.

Exactly. I'd put it on the shadow list together with COMPLEMENT and
CONTINUE. It is good that CLISP seems to warn about redefining symbols
in the CL package - I'd be surprised if INTERSECTION and TYPE-ERROR
are the only ones.
