```suggestion underlying types is available in Objective-C. Use ``__has_extension(c_fixed_enum)`` to determine whether support for fixed underlying types is available in C prior to C23. This will also report ``true`` in C23 and later modes as the functionality is available even if it's not an extension in those modes.
