;;; Another patch is included more for information than anything --
;;; removing the descriptor-reg SCs from the CHECK-BOUND vop in
;;; x86/array.lisp seems to allow that file to compile without error[*],
;;; and build; I haven't tested rebuilding capability, but I'd be
;;; surprised if there were a problem. I'm not certain that this is the
;;; correct fix, though, as the restrictions on the arguments to the VOP
;;; aren't the same as in the sparc and alpha ports, where, incidentally,
;;; the corresponding file builds without error currently.
;;; Since neither of us (CSR or WHN) was quite sure that this is the
;;; right thing, I've just recorded the patch here in hopes it might
;;; help when someone attacks this problem again:
