`mailp' is used implicitly through the variable `gnus-group-highlight'
which is let-bound to `list'. `list' is used in the body of the
let-form.

Hm, I can't reproduce the warning using `emacs-lisp-byte-compile' with
GNU Emacs 23.0.50.6 (i686-pc-linux-gnu, GTK+ Version 2.10.6) of 2007-10-20.
Too old?
Bye, Reiner.
