seed_rng.hpp gives warning on gcc 4.1.2

[Leonid Gershanovich <gleonid@…>]

I am getting a warning in default generator_iterator ctor.

template <class Generator>
class generator_iterator

: public iterator_facade<

generator_iterator<Generator>

, typename Generator::result_type
, single_pass_traversal_tag
, typename Generator::result_type const&

{

public:

generator_iterator() : m_g(NULL) {}
generator_iterator(Generator* g) : m_g(g), m_value((*m_g)()) {}

...

private:

Generator* m_g;
typename Generator::result_type m_value;

};

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.
