<pre>std::complex<T> is required to have the same *memory* representation as
_Complex T, but it is *not* required to have the same representation when used
as a return type.
The representations as return types differ on i386-linux-gnu, for instance
(_Complex float is returned in a pair of integer registers; std::complex<float>
is returned by sret). Clang's warning is correct and appropriate.</pre>
