I had some problems with lexical_cast and not using wchar_t as a built-in
type. For instance...

std::stringstream ss;
ss << boost::lexical_cast<unsigned short>("23");

lexical_cast would return a wstring, and a compile failure, because
internally there is a the template that matches unsigned short as wchar_t,
which makes lexical_cast return a wstring. Or something like this. The fact
is that this example gives an cryptic compiler error (it was for me):

boost\lexical_cast.hpp(147) : error C2679: binary '<<' : no operator found
which takes a right-hand operand of type 'const
(or there is no acceptable conversion)

Maybe to avoid this kind of compiler error message, there's such requirement
of wchar_t being an native type.
