--- Comment #14 from John Marshall <John.W.Marshall at glasgow dot ac.uk> --- [In reply to Jeremy Huddleston Sequoia in comment #12] In the future, please file radars for these problems and ping me directly if you want. Issues in macOS headers don't get fixed if we don't know about them, and I'd prefer to fix the SDK itself than have GCC use fixup hacks. [snip] The __OSX_AVAILABLE_STARTING issue still exists in the GM SDK as it was never reported to Apple AFAIK. I've filed a radar now to track it: <rdar://problem/55937005>. Thanks for the advice. I reported this to Apple in early June (FB6125120), as noted in comment #4 above. Looking at it in feedbackassistant.apple.com<http://feedbackassistant.apple.com> today, there is no real indication anyone at Apple has ever read it. So that's unfortunate. John
