Hi

The following code doesn't compile with g++ 3.3.1 (it did compile with older g++ 
2.9.6):

#include <iostream>
#include <complex>
using namespace std;

int main(int argc,char *argv[])
{
  std::complex<float> cfpvar(0.08,0.08);
  std::complex<double> cdfpvar(1.11,1.11);
  cout << "cfpvar=" << cfpvar << endl;
  cout << "cdfpvar=" << cdfpvar << endl;
  cfpvar = static_cast<std::complex<float> >(cdfpvar); // g++ 3.3.1 wont compile
  cout << "cdfpvar=" << cdfpvar << endl;
  exit(0);
}
