Subject: 	* attr.c (pthread_attr_setscope): Fix struct pointer 
 indirection error introduced 2002-01-04. 	(pthread_attr_getscope):
 Likewise.         * pthread.dsp (SOURCE): Add missing source files.

./tests/:
        * exception3.c (main): Shorten wait time.
        * mutex7.c: New test.
        * mutex7n.c: New test.
        * mutex7e.c: New test.
        * mutex7r.c: New test.
        * mutex6.c: Modified to avoid leaving the locked mutex
        around on exit.
