Excellent idea. I was never in favor of switching to "clang" anyway. I would have preferred that the base "gcc" was updated to the latest stable version; however, too many people got their shorts in a bunch and that wasn't going to happen. This sounds like a smart, well thought out concept; therefore, it will probably be rejected. -- Jerry ♔ Disclaimer: off-list followups get on-list replies or get ignored.
