Ah, I misunderstood meaning of 'defaults to IEEE long double' in last review.
We can assume 'how the compiler was built' is the same as 'how the libc++ was
built'.
But when 'how the libc++ was built' conflicts with 'how the compiler compiles
current program', we expect a warning, right? If so, this looks reasonable.
