ok. what I would like to say that if the trivial implementation for
norm (x*x+y*y) overflow than the current implementation is also
overflow, so I can't see any reason why we use the advanced version.
may I miss another reason again, but there are a few moew clever 
people on this list who can explain it for me:-)
