The macro that opts out of `std::ranges::` functionality is called `_LIBCPP_HAS_NO_INCOMPLETE_RANGES`, and is unrelated to this macro which is specifically about _compiler_ support for the _syntax_. The only non-mechanical diff here is in `<__config>`. Differential Revision: https://reviews.llvm.org/D118507
