     Form of <base>:
 
          (__segment)__self
 
     A based pointer declared this way can address locations in only
     the segment in which the pointer itself is stored. Such pointers
     can save space in a linked list or tree if the entire data
     structure fits in a single segment.
 
     For example:
 
          typedef struct tree TREE;
 
          struct tree
          {
             int name;
             TREE __based( (__segment)__self ) *left;
             TREE __based( (__segment)__self ) *right;
          };
