Define __STDC_CONSTANT_MACROS at the start of the source *before* any std
lib headers are included, then include <boost/cstdint.hpp>. One potential
gotcha: note that the implementation of <boost/cstdint.hpp> may delegate to
the platform's stdint.h , so we're relying on that not being buggy.
boost::int64_t i = UINT64_C(0x1234567812345678);
