Without Rust exposing these symbols, the user would encounter a linker error when linking to +//! C/Objective-C/Swift libraries using these features. +//! +//!

Ideally, these symbols should probably have been a part of Apple's `libSystem.dylib`, both +//! because their implementation is quite complex, using allocation, environment variables, file +//! access and dynamic library loading (and emitting all of this into every binary). +//! +//! The reason why Apple chose to not do that originally is lost to the sands of time, but a good +//! reason would be that implementing it as part of `compiler-rt` allowed them to back-deploy this +//! to older OSes immediately. +//! +//! In Rust's case, while we may provide a feature similar to `@available` in the future, we will +//! probably do so as a macro exposed by `std` (and not as a compiler builtin).

This does mean that users that attempt to link C/Objective-C/Swift code _and_ use `#![no_std]` +//! in all their crates may get a linker error because these symbols are missing. Using `no_std` is +//! quite uncommon on Apple systems though, so it's probably fine to not support this use-case. +//! +//!
