"Fixed: The base template for std::char_traits is restored after being
removed in Xcode 16.3; it is still deprecated and is going to be removed
in a future release. Restoring the base template allows code that
attempts to instantiate char_traits with types that are not provided by
the Standard (for example, std::basic_string<long long> and similar) to
still compile, giving it more time to transition.

Included at the end of this post are the non-standard uses I found in
our code base.
