I have XCode 16.4 installed with macOS SDK 15.5. When building using that SDK, what is the oldest/minimum supported value for -mmacosx-version-min? Specifically, is -mmacosx-version-min=11.0 still supported? Also, has it been announced for macOS 26 what the oldest/minimum supported value will be for -mmacosx-version-min? Specifically, will -mmacosx-version-min=11.0 still be supported? Where would this be documented?
