gcc allows you to disable individual warnings. So using "-Wall -Wextra
-Wno-unused-parameter" will give you all of the good warnings with
none of the annoying unused parameter ones. In practice, this single
warning is the only one I've found in the entire set of -Wall -Wextra
to do more harm than good. Every other warning they have has, in my
experience, been completely legitimate. And -Wextra adds so many more
useful warnings that I'd never consider leaving it out.
