So we could fight warnings like this as they appear... but honestly, building ANGLE with -Wextra is too aggressive IMO. -Wextra is great for code that we control, where the burden of squashing warnings is relatively low. But with ANGLE, we have to either land fixes upstream, or carry them downstream forever. It doesn't make sense to bother with this for minor build warning fixes when upstream is clearly not using the same warning flags and/or same compiler that we do. So I suggest we simply disable -Wextra for all of ANGLE.
