And I guess we also need a similar fix in byte-opt.el?  I installed
it.

I also suddenly see another byte-compilation message:

    ELC      emacs-lisp/byte-opt.elc
  Compiler-macro error for cl--block-wrapper: (error "(setf seq-elt) is already 
defined as something else than a generic function")
  Eager macro-expansion failure: (error "(setf seq-elt) is already defined as 
something else than a generic function")

What causes this?
