// Only has typedefs or using statements, with #conditionals

// ALERT: the forward declarations of items in <boost/integer.hpp> need items
// from this header.  That means that <boost/cstdint.hpp> cannot #include this
// forwarding header, to avoid infinite recursion!  One day, maybe
// boost::uintmax_t and boost::intmax_t could be segregated into their own
// header file (which can't #include this header), <boost/integer.hpp> will use
// that header, and <boost/cstdint.hpp> could refer to <boost/integer.hpp>.
