AFAICT this really depends on how modern your compiler is and which warnings it may now enable by default.

Since you are very close from an accepted driver, you may want to squash potential warnings (and more) with doing a sparse build (make C=) which covers a bit more than what a traditional C compiler does.

Almost there!
