What platform are you compiling on?  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.
