        PPC allocate-vector fix, plus OpenMCL buildability ...
        ... write a 0 at the end of the allocated vector to ensure
            all of its pages are unprotected.  Otherwise if one is
            passed off to C (by READ-N-BYTES for example) the GC
            trigger can be hit in foreign code.  (Compare to SPARC)
        ... revert "#+cmu #+cmu a b" back to "#+cmu a #+cmu b",
            as OpenMCL and ACL's readers have buggy implementations
            of CLHS 2.4.8.17.
