// Purpose: Forward declare the template class known
// as vcl_complex<T> without the cost of including the
// header file. Also declare the two typedefs at the
// bottom.
// *** make sure this file is consistent with vcl_complex.h ***
//
// Note: the standard complex class is just std::complex<T>, so
// on an ISO compiler, no forward declaration header is needed.
