9773	Clang configuration does not set BOOST_HAS_INT128	Douglas Gregor	John Maddock	"The Clang configuration (boost/config/compiler/clang.hpp) never sets BOOST_HAS_INT128, even though Clang supports this feature. The fix is to add

// Clang has __int128 for some targets.
#if defined(__SIZEOF_INT128__)
#  define BOOST_HAS_INT128
#endif

into the aforementioned file."	Bugs	closed	To Be Determined	config	Boost 1.55.0	Problem	fixed
