    libstdc++: Remove <sstream> dependency from std::bitset::to_ulong() test
    There's no need to use a stringstream to test the to_ulong() member.
    This will allow the test to be used in freestanding mode.
            * testsuite/20_util/bitset/access/ Construct bitset
            from binary literal instead of using stringstream.
