Ok, will do. > Do you need to change the __SIZEOF_FLOAT128__ code at all now? I don't > see it? Yes, because the macro is from name about whether __float128 can be used and what it's size. On powerpc*, __float128 is a macro defined to __ieee128 under some conditions, so the condition to define __SIZEOF_FLOAT128__ should be that the macro is defined and __ieee128 can be used.
