Re: [boost] Visual Studio 2015 Update 3 has removed std::unary_functionand std::binary_function

A quick grep for these terms found 153 instances of "std::unary_function" and 118 of "std::binary_function" across several libraries, including accumulators, algorithm, config, container, function, gil, graph, icl, mpi, msm, polygon, ptr_container, serialization, smart_ptr, tr1, unordered, utility - and probably others.

Since a number of bind's tests use boost.function, which is under CMT, I'll take care of it (by adding typedefs.)
