[boost] Please use BOOST_ASSERT_MSG(x, "message") instead of BOOST_ASSERT(x && "message")

Several libraries, including Boost.Array, use things like BOOST_ASSERT( i < N && "out of range" ); This causes warnings with EDG-based compilers. It would be nice if library authors could replace this with something like BOOST_ASSERT_MSG( i < N, "out of range" ); Not only will it make those warnings disappear, it will also enable users to use those messages more efficiently in custom assert handlers. Thank you.
