* sysdeps/powerpc/bits/atomic.h (atomic_exchange): Remove unused
variable. Remove superfluous memory clobber.
* include/atomic.h: Syntax braino fix.
* posix/tst-nice.c (do_test): Use %m formats instead of printing errno
in decimal. Don't bail if niced at start. Just check that nice call
bumps the total at all.
