New description:

 I am using QNX SDB660 GCC 4.7.3 to create QNX C++ project. It is very
 simple like that.


 {{{
 #include <boost/thread/recursive_mutex.hpp>

 int main(int argc, char *argv[]) {
         return EXIT_SUCCESS;
 }


 It reports the following error.

 Is it QNX related or general bug for boost?
