--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
You can always use -fkeep-inline-functions to get the warning even for unused
inlines (by forcing them to be emitted). -Wnonnull-compare isn't the only
warning that isn't performed in the FEs early, think about -Wuninitialized and
-Wmaybe-uninitialized and many others. Those have the same behavior here.
