Hi Herve,

David and I just mailed about the issue and we agreed that it would be 
preferable to have such a function as a non-member.  Because tr1::array 
doesn't have such a c_array() member function and std::array probably 
won't have one either. Such a boost::get_c_array(arg) function 
(template) could be overloaded to support both std::array and 
boost::array.  For details, please have a look at
