I'm no expert, old or not, but I would prefer doing the minimum necessary to 
keep builds working. If that means slightly suboptimal code or diagnostics for 
long-obsolete OS X versions then so be it.

Yes, quite right. My only worry was whether Emacs has incorrect uses of __clang_major__ that cause incorrect user-visible behavior on some macOS versions. I'm not worried about suboptimal code or bogus warnings.

Perhaps I'm worrying too much. Not being an old Mac OS X expert (pun was intended :-) I don't know. If someone reading this email is such an expert and cares about old macOS ports I hope they can spare a few minutes to check.
