    PR libstdc++/48521
    * include/std/type_traits (result_of): Handle pointer to member.
    * include/std/functional (__invoke): Likewise.
    (_Function_to_function_pointer): Remove.

    unary_function and binary_function.
    (reference_wrapper::operator()): DR 2017.
    (ref(const A&&), cref(const A&&): Define as deleted.
    * include/std/future (async): Simplify SFINAE and use result_of to
    support pointer to member.

    member.
    * testsuite/20_util/reference_wrapper/24803.cc: Likewise.
    * testsuite/20_util/reference_wrapper/typedefs.cc: Test for types
    instead of derivation from unary_function and binary_function.
