[boost] [uitility/result_of] CodeGear support of result_of

Hi, Seemingly, CodeGear does not support boost::result_of http://tinyurl.com/8onbjj I propose that this is officially recognized so that including <boost/utility/result_of.hpp> results in BOOST_NO_RESULT_OF being defined rather than the current compile error. This will benefit those result_of-dependent libraries honoring BOOST_NO_RESULT_OF (vg. Boost.Parameter). Joaquín M López Muñoz Telefónica, Investigación y Desarrollo||* *
