[Bug libstdc++/12961] New: Problem with generic complex constructor

["Yves dot Renard at gmm dot insa-tlse dot fr" <gcc-bugzilla at gcc dot gnu dot org>]

The constructor for the template class std::complex<flt>
is different as the one for specialized complex classes
std::complex<float> std::complex<double> and std::complex<long double>

The one for the generic template :
complex(const _Tp& = _Tp(), const _Tp & = _Tp());

The one for std::complex<float>
complex(float = 0.0f, float = 0.0f);

When I use qd (a library for quatruple double) and 
std::complex<qd_real>
I cannot initialize that kind of complex with
std::complex<qd_real> x(1)
because the imaginary part is not initialized.

This does not allow me to build completely generic algorithm for my library
GMM++ (see http://www.gmm.insa-tlse.fr/getfem/gmm.html)
