[boost] Boost.Any and RTTI

Hi, I need a Boost.Any like facility that doesn't depend on RTTI, so I patched Boost.Any to utilize Boost.TypeIndex if BOOST_NO_RTTI is defined. The diff is available here; https://github.com/cdglove/any/commit/7188b13909a061495ef31f979b55f9779a9e99... Is there any interest in merging this into mainline? Or is someone working on a more correct patch than this? Thanks, -- chris
