2012 Update 3 supports XP targeting.

http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2012/n3462.html says:

"Implementation Experience
Has this been implemented yet? Yes. In c++std-lib-33002, Howard Hinnant claims that his libc++ library has already shipped a SFINAE-friendly result_of. In c++std-lib-33013, he links to his implementation. It can be found at http://llvm.org/svn/llvm-project/libcxx/trunk/include/type_traits.
Daniel Krügler claimed in a private exchange to have recently implemented a SFINAE-friendly result_of for gcc.
Also, Boost recently switched to a SFINAE-friendly result_of, although it hasn't shipped it yet at the time of writing (2012-09-20)."

You might want to do that for 2012 and earlier too, where std::result_of didn't work for movable-only arguments.
