The -Wall option has implied -Wunused-variable for a very long time; the idea as I understand it was to detect dead code which might be an indicator for other problems (typos or planned functionality that was left out) and which is distracting. As I understand it, the only reason -Wunused-but-set-variable did not exist until recently was a small accident of implementation, that technically "x = 5;" is an expression that evaluates "x". I believe the best way to avoid breaking the build is to simply not use -Werror on autobuilders. I would like to teach autobuilders to send warnings by email to interested maintainers so maintainers could get the benefit of notification without making the release team and toolchain maintainers' lives more difficult; would you be interested in that?
