[Coroutine] warning with GCC

[faithandbrave@…]

I am using GCC with -pedantic option. happen few warning.

#include <boost/coroutine/all.hpp>
#include <boost/foreach.hpp>

typedef boost::coroutines::coroutine<int()> coroutine;

void f(coroutine::caller_type& caller)
{
    caller(1);
    caller(2);
    caller(3);
}

int main()
{
    coroutine coro(f);

    BOOST_FOREACH (int x, coro) {
        std::cout << x << std::endl;
    }
}
