This function used to work fine in previous releases but doesn't now:

std::string decompress_gzip(const std::string& in)
{
        std::string res;
        bio::array_source src(in.data(),in.length());
        bio::copy(bio::compose(bio::gzip_decompressor(), src),
bio::back_inserter(res));
        return res;
}

I get this compile error:

home/code/boost_1_41_0/boost/iostreams/read.hpp:191: error: 'class
boost::iostreams::detail::direct_adapter<boost::iostreams::basic_array_source<char>
>' has no member named 'putback'
