[boost] GCC 4.3.0 is available (with some C++0x support)

GCC 4.3.0 has been released. It contains support for some new C++0x features in its experimental C++0x mode, including rvalue references, variadic templates, and decltype. Please see http://gcc.gnu.org/gcc-4.3/cxx0x_status.html for more information about the C++0x features available in this GCC release. Now would be a great time to start experimenting with C++0x features, to improve Boost libraries or just for fun. Or, come to BoostCon this year for some hands-on experience with the experts. - Doug
