[boost] Re: Test failure for basic_cstring_test

/boost/head-regression/boost/boost/test/test_tools.hpp:434: undefined reference to `std::char_traits<unsigned char>::compare(unsigned char const*, unsigned char const*, unsigned)'

For some reason there is no specialization of std::char_trairs for unsigned char. Does anybody knows a workaround, oher than like exlicit specialization in my code? Gennadiy.
