I haven't found one - gcc-4.7.2 has all sorts of __SIZEOF_XXX__ defines for every last type *except* __float128 and __float80 :-(
Sorry for a possibly stupid questio, but is it not possible to use any of the FLT128_XXX defines listed here:
http://gcc.gnu.org/onlinedocs/libquadmath/Typedef-and-constants.html#Typedef...
Including that header will only work (as in not generate a compiler error) if the compiler supports __float128 as a native type, which is what we want to work out... basically whether the GCC build was configured to support it or not. John.
