   This would require a C++ specific linker/loader which is not possible on   
   some systems. Perhaps because the OS manufacturer doesn't support 3rd   
   party tools at this level.   
      
   The current rules allow for the use of the available system tools, which   
   makes it possible to implement C++ on a few additional systems.
