ABI_CHANGE is not a valid name for a non-standard macro coming from
GCC or the runtime, because it's not in the reserved namespace.
Maybe you're trying to use the blog post as a tutorial for how to
achieve what you want, but it isn't that, it's just a brief
introduction to the topic. If it doesn't hold your hand through every
step that's because that wasn't its goal. Trying to follow it like a
tutorial isn't going to work.
