+ *
+ *	__link_set_decl(set, ptype)
+ *		Provide an extern declaration of the set `set', which

+ *		macro must be used by any code which wishes to reference
+ *		the elements of a link set.
+ *
+ *	__link_set_start(set)
+ *		This points to the first slot in the link set.
+ *
+ *	__link_set_end(set)
+ *		This points to the (non-existent) slot after the last
+ *		entry in the link set.
+ *
+ *	__link_set_count(set)
+ *		Count the number of entries in link set `set'.
+ *
+ * In addition, we provide the following macros for accessing link sets:
+ *
+ *	__link_set_foreach(pvar, set)
+ *		Iterate over the link set `set'.  Because a link set is
+ *		an array of pointers, pvar must be declared as "type **pvar",
