Note that this section of boost/config.hpp deals only with making
wchar_t visible in namespace std. Since nobody will ever refer to
wchar_t as std::wchar_t (either it's a distinct built-in type or it's
a global typedef), treating wchar_t the way it is now seems to be ok.

Good point. I've added a hint.
