 - libc++ no longer supports ``std::allocator`` and containers of 
``const``-qualified element type, such
   as ``std::vector`` and ``std::list``. This used to be 
supported as an undocumented extension.
   If you were using ``std::vector``, replace it with 
``std::vector`` instead. The
-  ``_LIBCPP_ENABLE_REMOVED_ALLOCATOR_CONST`` macro can be defined to 
temporarily re-enable this extension as
-  folks transition their code. This macro will be honored for one released and 
ignored starting in LLVM 20.

Note: the `temporarily re-enable` part seems to be duplicated.

@tru Thanks a lot for considering the patch! I just wanted to follow up to 
close the loop here -- would be awesome to either merge or close this patch, so 
that we can proceed with fixing our downstream issues according to the 
resolution. Thanks!

@tstellar Just wanted to bring this to your attention -- would be awesome if we 
could get this merged! We discovered this pretty late in the process, 
unfortunately, but it breaks a few users (and results in frustratingly cryptic 
linker errors).
