Avoid using the "unnamed struct field" extension (enabled with -fms-extensions). This feature/extension silently does the wrong thing in g++. As far as I can tell, g++ simply throws the field away entirely (note that it works fine with gcc). Since I am now always casting the object (for other reasons), accessing protected/public fields simply requires the cast refer to the defining class. This solution is simpler all around (thanks to Chris for suggesting it).
