* 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.
