@steven_wu Thanks for fixing the text.

I can't comment on the use of `.private_extern` because I'm not familiar with it. Using the `VISIBILITY_HIDDEN` macro which seems to be defined by `darwin_add_builtin_libraries()` seems reasonable. I don't know about the OS builtin libraries though. Any thoughts @kledzik ?
