This is great. It really showcases zig's dedication to quality, IMO. I wish they took the time to communicate the intricacies of their toolchain.

Some things I think are remarkable:

Contrary to Rust, zig allows to cross-compile to MacOS. I think this implies that zig needed to build a custom linker!

Regarding libc:

- On Linux libc is not required because zig is using syscalls directly - On MacOS libc is required because of the lack of stable abi - On Windows libc is not required because zig links to windows kernel dll.

To my understanding, this implies that a compiled zig program will work across all linux distributions!

For C integration, I'm not knowledgeable enough to fully appreciate the work being done. but the fact that the cross-compiling also works out-of-box is mind-blowing to me.
