 I am getting a warning in default generator_iterator ctor.

 template <class Generator>[[BR]]
 class generator_iterator[[BR]]
   : public iterator_facade<[[BR]]
         generator_iterator<Generator>[[BR]]
       , typename Generator::result_type[[BR]]
       , single_pass_traversal_tag[[BR]]
       , typename Generator::result_type const&[[BR]]
     >[[BR]]
 {[[BR]]
  public:[[BR]]
     '''generator_iterator()''' : m_g(NULL) {}[[BR]]
     generator_iterator(Generator* g) : m_g(g), m_value((*m_g)()) {}[[BR]]
 [[BR]]
     ...[[BR]]
 [[BR]]
  private:[[BR]]
     Generator* m_g;[[BR]]
     typename Generator::result_type '''m_value''';[[BR]]
 };


 Depending on resulting type of "typename Generator::result_type" it is
 possible that m_value member remains uninitialized when object created via
 default ctor.

 Please consider attached patch.
