I'm using macOS 11.2 20D5029f & Xcode 12.3 12C33 ... but the issue is with the implicitly defined C functions, not the beta OS

That does the trick! Thx!

Ok. I wait upstream to merge the patch. If they don't answer within 1 days I put the patch on macports. Happy new year to you and your family :)
