Hi,

does the boost filesystem support boost.range (or vice versa?) I've got
a compile error by

    fs::ifstream in( ... );
    std::string storage;
    boost::copy( in, std::back_inserter( storage ) );

using trunk

boost/mpl/eval_if.hpp: In instantiation of ‘boost::mpl::eval_if_c<true,
boost::range_const_iterator<boost::filesystem::basic_ifstream<char,
std::char_traits<char> > >, boost::range_mutable_iterator<const
boost::filesystem::basic_ifstream<char, std::char_traits<char> > > >’:

boost/range/iterator.hpp:63:   instantiated from
‘boost::range_iterator<const boost::filesystem::basic_ifstream<char,
std::char_traits<char> > >’
