std::unary_function<typename ArgumentType, typename ResultType> is:

) from C++03 (and C++98?)
) deprecated in C++11
) removed in C++17

Looks like the code is rather old relative to C++ standard vintages
and might need to be built via the likes of -std=c++03 use for its
original/unmodified content?
