K&R2 in section 6.7 Typedef (on page 146) shows exactly how to do this 
with typedefs, and the above example would be:

    typedef struct _struct2 *STRUCT2ptr

    typedef struct _struct1 {
        .....
        STRUCT2ptr structure;
        .....
    } STRUCT1;

    typedef struct _struct2 {
 	   .....
 	   STRUCT1 *structure;
 	   .....
    } STRUCT2;
