Subject: [PATCH] Work through tests with 'cray.hpp'

- Almost everything is passing. The only thing that's failing is
  'limits_test.cpp', which is failing tests on lines 160 and 161 (shown
  below).

  if(lim::is_iec559)
  {
    BOOST_TEST(! (qnan == qnan)); # __LINE__ == 160
    BOOST_TEST(qnan != qnan); # __LINE__ == 161
  }
