AFAIK, these are new checks. I get similar warnings on Fedora for different flags. > I have never seen this before and I haven't (to my knowledge) set any > compilation flags.

Again AFAIK (there are package maintainers for several distros here that can correct me if I'm wrong), each distro defines some policies regarding compilation flags that are applied to all packages by default. So these warnings can be safely ignored locally (or you may override them), because those flags won't be defined on CRAN.
