Until now `cl-defstruct` signaled an error when encountering an unknown option. It's easy to code and it does the job, but it doesn't give good location info in the compiler's output, and it makes it more painful to use not-yet-supported options. So just signal a warning instead. * lisp/emacs-lisp/cl-macs.el (cl-defstruct): Warn about unknown options, instead of signaling an error.
