These macros seem overall fine, we normally organize our headers a bit differently. The macros should go in `llvm-libc-macros/sys-queue-macros.h`, which will leave this header practically empty. That's fine though, since that will allow you to use the path `include/llvm-libc-macros/sys-queue-macros.h` in your test which should make it guaranteed to grab the right file.
