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.
