Annex C (informative) Compatibility [diff]

C.4 C++ and ISO C++ 2014 [diff.cpp14]

C.4.9 Clause [utilities]: General utilities library [diff.cpp14.utilities]

[func.wrap]
Change: Constructors taking allocators removed.
Rationale: No implementation consensus.
Effect on original feature: Valid C++ 2014 code may fail to compile or may change meaning in this International Standard. Specifically, constructing a std::function with an allocator is ill-formed and uses-allocator construction will not pass an allocator to std::function constructors in this International Standard.
