-Subject: [PATCH] Update absl::allocator_traits and absl::pointer_traits to
- always use std::allocator_traits and std::pointer traits.
-
-Note that the reason given in the comments for these implementations was
-incorrect. Both of these exist in C++11, but not all compilers had
-working implementations, so Abseil backfiled them. All supported compilers
-now have working implementations.
-
-https://en.cppreference.com/w/cpp/memory/allocator_traits
-https://en.cppreference.com/w/cpp/memory/pointer_traits
-
-Documentation has been updated to recommend the std:: spellings.
-
-Fixes #1366
