When the include path contains the Watt-32 header directory multiple times, #include_next breaks, since two headers have it located inside the include guard.
This scenario can happen when a project builds a local copy of Watt-32, but the user has their own copy in the global include path already. In this case we want to use the local version of the header, so the recursive #include_next must be placed at the end of the header file.
