The incredible thing is this is actually the result of an explicit design decision.

The compiler accepts most GCC flags. Unrecognized flags (e.g., architecture- specific -m flags, unknown -f flags) are silently ignored so ccc can serve as a drop-in GCC replacement in build systems.

They're so committed to vibing that they'd prefer if the compiler just does random shit to make it easier to shove it haphazardly into a build pipeline.
