This is the stuff designed to make nice follow the
SUS spec:

RETURN VALUE
  Upon successful completion, nice() returns the new nice value
  minus [NZERO]. Otherwise, -1 is returned, the process' nice
  value is not changed, and errno is set to indicate the error.

This is not the same as traditional Linux nice has done,
where 0 indicates success and -1 failure.

Someone from Debian has objected to this change being
required in case something depends on the old behavior.

The patch is described on the LSB Testing FAQ page:

http://www.linuxbase.org/test/lsb-runtime-test-faq.html

as fixes for T.nice 7,8.  That patch is incomplete;
the other piece of it is that a stub
sysdeps/unix/sysv/linux/nice.c must be added which
contains only "#include <sysdeps/unix/nice.c>"
so that the glibc build system will pick it up
in a build-for-Linux.
