 The following simple patch seems to make GCC a whole lot happier:

 +  namespace { KIND##_##NAME##_t const KIND##_##NAME = {}; }   \
    BOOST_INSTALL_PROPERTY(KIND, NAME)
  #endif

 }}}

 I haven't tested it against the trunk tests but if you are willing to try
 and see what breaks, I would be happy to apply it in trunk if you give me
