That's true, but I don't think anyone expects unboxed arrays.  I find
"typed" confusing because everything has a type.  Maybe acl's
immediate-arg is better?  But cmucl already has a concept of immediates,
so this can be confusing too.

So, how do I build your changes?  I assume can just do a normal
cross-compile using tccxboot.lisp?
