Comment (by anonymous):

 So a possible fix would be to add:

 {{{
 #if !defined(BOOST_NO_CXX11_RVALUE_REFERENCES) \
   && defined(__APPLE__) && defined(_GLIBCXX_VERSION) \
   && (_GLIBCXX_VERSION <= 20070719)

 // move and forward go here

 #endif
 }}}

 But where do we add this?  The obvious place is in config/suffix.hpp but
 as move/forward depend on remove_reference that's a really bad idea
 (cyclic dependencies etc).  Does clang have an intrinsic for
 remove_reference?  If so we could make it a clang specific fix in
 clang.hpp I guess...

 John.
