How will it actually work without rtti? I think boost::any pretty much requires it.

Yes, I've also submitted a patch to boost::any. Actually I'm not quite sure about how will go on with detail/typeinfo.hpp, when there is the new library type_index in 1.56.0.

I'm trying boost::program_options 1.56 release with "-fno-rtti" flag and i'm getting error:

/softdev/boost-1.56/include/boost/any.hpp:149:48: error: cannot use typeid with -fno-rtti

return content ? content->type() : typeid(void);

can i use boost::program_options with no rtti?

Using type_index to avoid RTTIs.

Since boost::any has switched to boost::type_index, also using type_index here is reasonable to remove rtti.
