[Boost-users] BOOST_CHECK_EQUAL and std::wstring

I am using the Boost unit test suite for the first time, but am having a 
problem using BOOST_CHECK_EQUAL with wide strings.  For example:

    std::wstring str1 = L"unit";

    std::wstring str2 = L"test";

    BOOST_CHECK_EQUAL(str1, str2);

This produces the following error:

c:\boost\include\boost-1_33_1\boost\test\test_tools.hpp(274) : error C2679: 
binary '<<' : no operator found which takes a right-hand operand of type 
'const std::wstring' (or there is no acceptable conversion)

Any help would be appreciated.
