These changes prevent "dyld[678]: symbol not found in flat namespace" for several symbols. Xcode 13 and/or Monterey has stricter checks for undefined symbols. Note that binaries running on macOS 12, but built on macOS 11 with Xcode 12, don't trigger these checks for some reason.

I believe it is due to ZOL moving to "-fvisibility=hidden" for libraries, which appears to be ignored (not supported?) in XCode 12. |

We'll need to check if these changes are still necessary (and if any other changes are needed) with macOS Monterey 12.0.1, which was released today. |
