You can either modify `__config` to undefine those macros in the source, or you can start opting into individual ABI flags instead of opting into all of them by switching from `LIBCXX_ABI_VERSION = 2` (in CMake) to `LIBCXX_ABI_DEFINES` (in CMake). Depending on your use case, it may be simpler to just undefine the two macros locally for your transition period or to switch to a purely opt-in approach for ABI flags, but both work.
