Hi,

With recent versions of boost I get lots of warnings like the following:

/.../boost/uuid/seed_rng.hpp: In member function ‘void 
boost::uuids::detail::seed_rng::sha1_random_digest_()’:
/.../boost/uuid/seed_rng.hpp:157:24: warning: variable ‘not_used’ set but not 
used [-Wunused-but-set-variable]

I'm using GCC 4.6 with -Wall. It's trivial to mask this warning out by 
attaching __attribute__((unused)) to the variable, which I've done locally. Ok 
to commit?
