+ * 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

* 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.
