Are string typedefs generally useful in C++03? E.g. does
std::char_traits<boost::char16>::length() work? It would be needed if one to
construct u16string from a literal. If not these typedefs should not be
exposed to users, IMHO.
Otherwise, cstdint.hpp is in Boost.Config, and this header offers similar
functionality.
