Are you looking at anything else besides "unused code" warnings? In the Jenkins job, I put in the following in make.conf: # disable -Werror in userland build NO_WERROR=yes # disable -Werror in kernel build WERROR= With this, I build and get all the warnings: https://jenkins.freebsd.org/job/FreeBSD_HEAD_amd64_gcc4.9/4/warnings17Result/ If you commit stuff which deals with the warnings, it would be hepful if you can periodically monitor that Jenkins job and see if the overall warnings go down. Thanks. -- Craig
