Sprinkle in some asserts to make sure compilers aren't getting creative. This may introduce a new compiler dependency, as I suspect older versions of GCC don't support this syntax. It definitely needs a new compiler flag to suppress a warning when some fields are not explicitly initialized. If we've omitted a field, it's because it's a field we don't know (or care) about, and we want that thing initialized to zero. Signed-off-by: Zygo Blaxell <bees@furryterror.org>
