lexical_cast problem with Unicode

I have problems compiling the following piece of code under Microsoft Visual C++
6.0 with UNICODE defined. The compiler complains about a missing operator<<.
What can I do in order to get this programme compiled ?

#include <iostream>
#include <boost/lexical_cast.hpp>

int main( int argc, char * argv [] )
{
        std::wcout << boost::lexical_cast<std::wstring>( std::wstring( L"test" )
).c_str() << L"\n";

        return 0;
}

c:\programme\boost_1_30_0\boost\lexical_cast.hpp(148): error C2679: binary '<<':
no operator defined which takes a right-hand operand of type 'const wstring' (or
there is no acceptable conversion)

c:\programme\boost_1_30_0\boost\lexical_cast.hpp(146): while compiling
class-template member function 'bool
boost::detail::lexical_stream<wstring,wstring>::operator <<(const wstring &)'

Thanks in advance,
        Stefan
