[Bug c++/30431] New: failure to check for visible declaration of friend function to template class

[tkapela at poczta dot fm]

/ There should be no difference where friend declaration is made 
// inside class. But in fact at least under GCC 4.1.1 there is.


template <typename T>
class CTest;

template <typename T>
T foo(const CTest<T> &test)
{
  return test.m_data;
}

template <typename T>
class CTest{
  public:
    // In this place we can declare friend function foo
    //friend T foo<>(const CTest &test);

    T foo()
    { return m_data;}  

    // But in that place we can  not declare friend function foo
    friend T foo<>(const CTest &test);

  private:
    T m_data;
};


int main()
{
  return 0;
}
