-/**
- * This is a hack to make RGBDS build on macOS 10.14 and below. Without it, we get errors like:
- *     error: 'path' is unavailable: introduced in macOS 10.15
- * The hack weakens the `std::filesystem::path` availability error into a warning, by removing
- * `strict` from the availability macros (for information on the `availability` attribute, see
- * https://releases.llvm.org/17.0.1/tools/clang/docs/AttributeReference.html#availability). This is
- * acceptable because what we need of `std::filesystem::path` was already supported in macOS 10.14
- * (the last version to support 32-bit, hence in demand despite being superseded by 10.15 in 2019).
