Annex C (informative) Compatibility [diff]

C.6 C++ and ISO C++ 2003 [diff.cpp03]

C.6.10 [utilities]: general utilities library [diff.cpp03.utilities]

Affected subclauses: [refwrap], [arithmetic.operations], [comparisons], [logical.operations], and [bitwise.operations]
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Rationale: Superseded by new feature; unary_function and binary_function are no longer defined.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 revision of C++.
