Has anyone noticed that in src/hyp.lisp, maxima defines a function INTERSECTION? With Clisp, I get a warning about redefining the COMMON-LISP function INTERSECTION. In CMUCL, it is, indeed, redefined so that you can't use the common-lisp function anymore. Ray P.S. Clisp also complains about redefining TYPE-ERROR when running (save-maxima).
