c++ - template functions and namespaces

Here are two test-cases:

namespace N
{
  template<class T> void f(T a)
  { }
  // Error: 'f' is already defined

  template<class T>
  struct A
  {
    A(T a)
    {
      f(a);
    }
  };
}


int main(int argc, char *argv[])
{
  N::A<int> a(3);

  return 0;
}


and:


namespace N
{
  template<class T> void f(T a)
  { }

  template<class T> void g(T a)
  {
    f(a);
    // Error: function 'f' has no prototype
    // it works if I use N::f(a) here
  }
}


int main(int argc, char *argv[])
{
  N::g(3);

  return 0;
}
