mkmf sets `:werror => true` by default, which I think is a mistake.  I have a patch in #13069 that turns off `:werror` by default, though users can still set `$werror = true` if they want that behavior.

Last ruby-loco build has warnings & test failures after 61097.  Build log (attached) has 329 instances of:

Thanks, Greg
