New description:

 `std::unary_function` and `std::binary_function` from libc++ are
 deprecated in the macOS 13 SDK, and disabled by default in LLVM.org Clang
 15 and the macOS 14 SDK when building with C++17 or later (unless
 `_LIBCPP_ENABLE_CXX17_REMOVED_UNARY_BINARY_FUNCTION` is defined).
 Examples:

 {{{
 compress.cpp:40:26: error: no template named 'binary_function' in
 namespace 'std'; did you mean '__binary_function'?
 struct _Fit: public std::binary_function<int, int, bool>
                     ~~~~~^~~~~~~~~~~~~~~
                          __binary_function
 }}}

 {{{
 qtesttable.cpp:141:35: error: no template named 'unary_function' in
 namespace 'std'; did you mean '__unary_function'?
 class NamePredicate : public
 std::unary_function<QTestTablePrivate::Element, bool>
                              ~~~~~^~~~~~~~~~~~~~
                                   __unary_function
