the latter two are inside an extern "C" block, meaning their initial C++ linkage (by virtue of them being static class members) conflicts with the now C linkage, also the comment there states the AwtComponent fields are supposed to be set here, and I have no idea why this was not done, so I moved them all to be under that comment
