------------------------------------+---------------------------------------
 message_queue compiled with gcc 3.4.6 in boost 1.47.0.

 On CentOS release 5.7:


 {{{
 $ cd boost_1_48_0/libs/interprocess/example
 }}}


 gcc 4.4 works fine:


 {{{
 $ g++44 -I/opt/rotateright/include -L/opt/rotateright/lib -lboost_thread
 comp_doc_message_queueB.cpp -o test
 $
 }}}


 but gcc 3.4:


 {{{
