11661	BOOST_NO_UNREACHABLE_RETURN_DETECTION to use __builtin_unreachable()	akrzemi1	John Maddock	"Macro BOOST_NO_UNREACHABLE_RETURN_DETECTION is now defined as:

{{{
#ifdef BOOST_NO_UNREACHABLE_RETURN_DETECTION
#  define BOOST_UNREACHABLE_RETURN(x) return x;
#else
#  define BOOST_UNREACHABLE_RETURN(x)
#endif
}}}

In order to take the full advantage of the compiler widgets, I think it could be changed to:

{{{
#ifdef BOOST_NO_UNREACHABLE_RETURN_DETECTION
#  define BOOST_UNREACHABLE_RETURN(x) return x;
#else if __HAS_BUILTIN_UNREACHABLE
#  define BOOST_UNREACHABLE_RETURN(x) __builtin_unreachable()
#else
#  define BOOST_UNREACHABLE_RETURN(x)
#endif
