+ * state The state of the type. The state represents whether the
+ * layout of the type is undefined or fixed (values: layout_undefined
+ * or layout_fixed). Compound types can have an undefined
+ * layout. The layout of the basic types primitive and pointer
+ * is always layout_fixed. If the layout of
+ * compound types is fixed all entities must have an offset
+ * and the size of the type must be set.
+ * A fixed layout for enumeration types means that each enumeration
+ * is associated with an implementation value.
* visit A counter for walks of the type information.
+ * link A void* to associate some additional inforamtion with the type.
*
* These fields can only be accessed via access functions.
