[boost] detail/atomic_count_gcc.hpp error

trying to do:

    boost::detail::atomic_count c(0);
    std::cout << long(c) << std::endl;

with gcc 3.2.2 gives:

    /usr/include/boost/detail/atomic_count_gcc.hpp: In member function
       `boost::detail::atomic_count::operator long int() const':
    /usr/include/boost/detail/atomic_count_gcc.hpp:46: invalid conversion from `
       const _Atomic_word*' to `volatile _Atomic_word*'

in the following function:

    operator long() const
    {
        return __exchange_and_add(&value_, 0);
    }

The problem can be solved by making the private member "_Atomic_word
value_" mutable.

ps I know I shouldn't use detail/* stuff directly...
