--- Comment #26 from Vincent Lefèvre <vincent-gcc at vinc17 dot net> --- (In reply to GCC Commits from comment #25) > -Wunused or -Wall or -Wunused -Wextra or -Wall -Wextra turn on [...] This looks wrong. If I understand what has been added to gcc/doc/invoke.texi, unused-but-set-parameter and unused-but-set-variable need to be distinguished here.
