Hi,

The test for the move library and the intrusive constainers pass on gcc-3.4.4 under cygwin, but I have some trouble chile compiling interprocess. I had no problems while compiling the 1.38.0.

It seems that the fact to declare the variable m_nOwner interprocess_recursive_mutex.hpp volatile break on this compiler.

   volatile detail::OS_systemwide_thread_id_t   m_nOwner;

On 1.38.0
   detail::OS_systemwide_thread_id_t   m_nOwner;

        detail::OS_systemwide_thread_id_t th_id = detail::get_current_systemwide_thread_id();
43    if(detail::equal_systemwide_thread_id(th_id, m_nOwner)){

The move semantincs one
   volatile detail::OS_systemwide_thread_id_t   m_nOwner;

        const detail::OS_systemwide_thread_id_t thr_id = detail::get_current_systemwide_thread_id();
42    const detail::OS_systemwide_thread_id_t old_id = m_nOwner;
        if(detail::equal_systemwide_thread_id(thr_id , old_id)){

Any ideas?

Best,
Vicente
