[boost] new macro request

Hi, In shared_ptr.hpp, line 560 there is code that reads #if defined(__GNUC__) && (__GNUC__ < 3) template<class Y> std::ostream & operator<< (std::ostream & os, shared_ptr<Y> const & p) { blah blah blah Can we have a boost macro for this that says whether we have old style iostreams (or is there one I missed? - the closest I could find was BOOST_NO_STRINGSTREAM) so I can compile this on my cheesy compiler without having to edit the boost source? (This was the only compilation error I got on upgrade to 1.35 with my unsupported embedded compiler) Thanks Andrew
