Milestone:  To Be Determined              |   Component:  interprocess
  Version:  Boost 1.36.0                  |    Severity:  Problem

------------------------------------------+---------------------------------
 There is a usage of a deprecated function in Visual Studio 8.0 (2005) when
 using the message_queue in the interprocess library.  However, this ONLY
 manifests itself when there is a #include <string> BEFORE the #include
 <boost/interprocess/ipc/message_queue.hpp>.  If the string include is
 after the message_queue include, everything compiles fine.

 For example:

 {{{
 #include <string>
 #include <boost/interprocess/ipc/message_queue.hpp>
 #include <iostream>

 int main(int argc, char* argv[])
 {
    boost::interprocess::message_queue* rcv;
    std::string exampleString = "Hi";

    std::cout << exampleString << &rcv << std::endl;
    return 0;
 }

 }}}
 returns the warning

 {{{

 1>c:\program files\microsoft visual studio 8\vc\include\xutility(2404) :

 msg_hdr_ptr_t*,boost::interprocess::detail::mq_hdr_t::msg_hdr_ptr_t*>(_BidIt1,_BidIt1,_BidIt2)'
 being compiled
 1>        with
 1>        [
 1>            _BidIt2=boost::interprocess::detail::mq_hdr_t::msg_hdr_ptr_t
 *,
 1>            _BidIt1=boost::interprocess::detail::mq_hdr_t::msg_hdr_ptr_t
 *
 1>        ]
 }}}
 however if I do:

 {{{
 #include <boost/interprocess/ipc/message_queue.hpp>
 #include <string>
 #include <iostream>

 int main(int argc, char* argv[])
 {
    boost::interprocess::message_queue* rcv;
    std::string exampleString = "Hi";

    std::cout << exampleString << &rcv << std::endl;
    return 0;
 }

 }}}
 then everything builds without any warnings.
