I'd like to confirm you made sure the built-ins *were type-generic* in the 
relevant versions of clang (not just that they existed there - in GCC, 
some of the built-ins were added first as type-specific for double, which 
would have made them inappropriate to use with long double, and then later 
changed to be type-generic).
