What's new in Emacs 27 is auth-source now does
(require 'cl-lib)
instead of
(eval-when-compile (require 'cl-lib))
lisp/auth-source.el: Depend on cl-lib unconditionally

In turn, url-parse does
(require 'auth-source)
and erldoc does
(eval-when-compile (require 'url-parse))
(require 'cl-lib)
This combination seems to confuse the byte-compiler.
