keywords, owner, component changed

keywords foreach removed
owner changed from Eric Niebler to Thorsten Ottosen
component foreach → ptr_container

This test case shows the problem is specific to ptr_container and has nothing to do with BOOST_FOREACH.

#include <boost/ptr_container/ptr_map.hpp>
int main()
{
    typedef boost::ptr_map<int, int> test_map_type;
    test_map_type test_map;
    test_map_type::const_reference r = *test_map.begin();
}

For me, this gives:

1>f:\scratch\scratch\main.cpp(9): error C2440: 'initializing' : cannot convert from 'boost::ptr_container_detail::ref_pair<F,S>' to 'boost::ptr_container_detail::ref_pair<F,S>'

Discovered that switching compiler flag to c++11 resolved the problem. Maybe this problem is specific to GNU compiler without c++11 enabled?

I was seeing it on msvc 2013.
