Subject:         * exception3.c (terminateFunction): For MSVC++, call        
 exit() rather than pthread_exit(). Add comments to explain         why.

        * rwlock2_t.c: New test.
        * rwlock3_t.c: New test.
        * rwlock4_t.c: New test.
        * rwlock5_t.c: New test.
        * rwlock6_t.c: New test.
        * rwlock6_t2.c: New test.
        * rwlock6.c (main): Swap thread and result variables
        to correspond to actual thread functions.
        * rwlock1.c: Change test description comment to correspond
        to the actual test.
