Thanks, Jonathan. I am, in fact, so certifying.
I do believe that bringing up support for new OS versions is in scope for
open branches, and it makes sense to merge, particularly for a trivial and
uncontentious patch like this one.

The macOS 13 SDK (and equivalent-version iOS and other Apple OS SDKs)

This collides with the use of __null_terminated in libstdc++'s

To add a module initializer optimization, we need to defer finishing
writing out the module file until the end of determining the dynamic
initializers. This is achieved by passing some saved-state from the main

It's simpler to just emit a static fn do do that, and add it onto the
