C23 auto is basically __auto_type so let's wrap it if our compiler doesn't provide it (yet). This lets us use `auto` as type specifier, e.g. compare enum libinput_config_status status = libinput_device_config_set(...) auto status = libinput_device_config_set(...) Note that as of now meson will never detect this as it requires -std=c23 to be passed to the compiler. This flag is only supported by Clang 18 (released 2024) and we don't want to break things for older compilers for what is a bit of a niche feature right now.
