I've added minimal __float128 support in Boost.Math Trunk: it's enabled whenever BOOST_MATH_USE_FLOAT128 is set, which it is automatically when the above macro is detected (which I note libstdc++ doesn't seem to use anywhere itself).

It's used in #if !defined(__STRICT_ANSI__) && defined(_GLIBCXX_USE_FLOAT128) template<> struct __is_floating_point_helper<__float128> : public true_type { }; #endif
