That -W switch was added to dmd's call to cpp very recently. No, you are not seeing this because you're building with an outdated toolcahin. I'm building master, everything is broken since https://github.com/dlang/dmd/pull/14801 CI is also broken when updating to latest toolchain, so I've had to revert it here: https://github.com/dlang/dmd/pull/14824 --
