Cool. I'll do the config parts then if this approach looks like it will fly.

I'll go through and do this for real. I messed up the pow bits too.

However, I think we still need the else part, because without it there
will be undefined references to functions that take C99 complex double.
(ie looking for __complex__ float not std::complex<float>). So, that
needs to either be fixed in the else clause or in complex::__rep().

Anyway.
