std::complex instantiation

[Lisandro Dalcin]

In 'src/sys/objects/init.c', we have

#if defined(PETSC_COMPLEX_INSTANTIATE)
template <> class std::complex<double>; /* instantiate complex template class */
#endif

Is this right? I believe it should be (regarding 'include/petscmath.h')

template <> class std::complex<PetscReal>;

or perhaps better:

#if defined(PETSC_USE_SINGLE)
template <> class std::complex<float>;
#elif defined(PETSC_USE_LONG_DOUBLE)
template <> class std::complex<long double>;
#elif defined(PETSC_USE_INT)
template <> class std::complex<int>;
#else
template <> class std::complex<double>;
#endif
