Close!

Actually it says "might not be defined at
runtime" :)

And it only mentions `cl-find-if' - not
`cl-caddr' or `cl-case' (?). Perhaps they have
some different status or location within the
CL library?

Also, looking at the fallout below, is it
likely that `eval-and-compile' (N.B. -and-, not
-when-) is what they meant in
(info "(elisp) Warning Tips") ?

Here is the compilation function:

    #! /bin/zsh
    compile-one () {
        local file=$1
        emacs -Q -batch -f batch-byte-compile $file
    }

Using functions form `cl-lib', and not doing
anything about it:

    In end of data:
    wrap-search-cp.el:133:1:Warning: the
    following functions are not known to be
    defined: cl-find-if, cl-caddr, cl-case

using (require 'cl-lib)

    no errors or warnings

using (eval-when-compile (require 'cl-lib))

    In end of data:
    wrap-search-cp.el:133:1:Warning: the
    function `cl-find-if' might not be defined
    at runtime.

using (eval-and-compile (require 'cl-lib))

    no errors or warnings
