+// [nathan] We have a zero sized array extension, and (unfortunately) allow it
+// to be the sole member of a struct (rather than the trailing member of a
+// non-empty struct as C99 is/will allow). Such a type will have a size of
+// zero. Internally, we also use a TYPE_SIZE of zero to indicate an
+// incompletable type. We must keep the two zeroes distinct -- arrgh!
