Well, as was shown with the earlier lexical_cast, g++ 2.95 does have
std::stringstream, but not std::basic_stringstream. This shows that even if
it has stringstream, it doesn't have the wide character version of it. This
means it can't be used with wide characters with lexical_cast. So this has
to be signalled somehow to lexical_cast. Any macro might do, but as it has
only partial stringstream support, defining BOOST_NO_STRINGSTREAM seems
reasonable. An alternative is to create a macro for partial support, but the
end result is the same for lexical_cast: No wide character support for that

I think the evidence can't be much clearer. :)
The rest appears to be cascading errors, but this is the first reported one.
