Change: Standard function object types no longer derived from std​::​unary_­function or std​::​binary_­function.

Rationale: Superseded by new feature; unary_­function and binary_­function are no longer defined.

Effect on original feature: Valid C++ 2003 code that depends on function object types being derived from unary_­function or binary_­function may fail to compile in this International Standard.
