Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
Write a file /tmp/foo.el with contents:
--8<-----------------------------cut here---------------start------------->8---
(defun foo-find ()
(require 'find-lisp)
(find-lisp-find-files default-directory "\\`foo.*"))
--8<-----------------------------cut here---------------end--------------->8---
emacs -Q /tmp/foo.el
M-x elint-current-buffer RET
;; It shows:
foo-fail.el:1:Error: Call to undefined function: find-lisp-find-files
Same if you wrap `find-lisp-find-files' call inside
`with-no-warnings', even if you wrote before the function
definition:
(declare-function 'find-lisp-find-files "find-lisp" (directory regexp))
This is a false alarm: when `foo-find' is called `find-lisp-find-files' is
called right after
(require 'find-lisp)
so that it's already defined.
It would be good if elint is smarter so that it does not report these cases.

I've now made elint in Emacs 28 load files that are `require'd, which
seems to fix this problem. I've next to no experience using elint,
though, so somebody please let me know if the leads to any problems.
