Yes. Please don't try to "fix" the warnings pointed out by that
completely broken warning.

I don't understand why some people seem to think "more warnings good".

-Wsign-compare is actively detrimental, and causes people to write
worse code (and often causes mindless type conversions that then
result in actual real bugs).
