AFAIK, contrary to Ada, Common Lisp does not try to enforce particular
behaviors with respect to compilation warnings.

Just to put things in perspective, this message only occurs for uses of
`declare' which use declarations not supported directly by Elisp
(that's fairly uncommon) and only for those `declare's that are inside
a `defun' rather than a `defun*' (even less common), and then only for
code that's not byte-compiled.
That's sufficiently rare that I'm not worried about it.
