Unnamed temporary type not being parsed correctly:

/usr/local/gcc-3.0/bin/g++ -Wall -o test Main.cpp
Main.cpp: In function `int main()':
Main.cpp:49: type specifier omitted for parameter
Main.cpp:50: type specifier omitted for parameter
Main.cpp:42: warning: unused variable `class2 c'
Main.cpp:43: warning: unused variable `class2 d'
Main.cpp:44: warning: unused variable `class2 e'
Main.cpp:45: warning: unused variable `class2 f'
Main.cpp:46: warning: unused variable `class2 g'
>How-To-Repeat:

#include <iostream>


//----------------------------------------------------------------------
class class1 {
public:
  explicit class1(double a) {
    data = a;
  }
  double data;
};
//----------------------------------------------------------------------

//----------------------------------------------------------------------
class class2 {
public:
  class2(class1 a, float t) {
    std::cout << "class2(" << a.data;
    std::cout << ", " << t << ")\n";
  }
  class2(float t, class1 a) {
    std::cout << "class2(" << a.data;
    std::cout << ", " << t << ")\n";
  }
};
//----------------------------------------------------------------------

//----------------------------------------------------------------------
int main() {

  double pir = 3.14159;
  class1 a(pir);
  class1 b(3.14159);

  std::cout << "Test 1 ";
  std::cout << a.data << ", ";
  std::cout << b.data << "\n";

  std::cout << "Test 2 ";
  float t2 = 1.5;
  class2 c(class1(3.14159), t2);
  class2 d(a, t2);
  class2 e(b, t2);
  class2 f(t2, class1(pir));
  class2 g(class1((double)pir), t2);

  // both should compile ????
  class2 h(class1(double(pir)), t2);
  class2 i(class1(pir), t2);

  return 0;
}
