--- Comment #22 from Jonathan Wakely <redi at gcc dot gnu.org> --- No, comment 1 was from Richard. And the warning already exists, and it says that a nonnull argument (i.e. something that can never be null) is compared to null. The only thing I'd change would be to change 'argument' to 'pointer'. Please stop reopening this to ask for the same thing, you're making yourself look silly. Either explain more clearly what you're asking for, or accept it already warns about this.
