FWIW, I just tried building Emacs from latest commit to look at it, but
it doesn't even build with `Error: void-function (rx)`.

Now, I know Emacs build system has some controversial design decisions
that were discussed a few months ago (which basically lead to errors
like that), so I tried removing `build/` dir completely and `find -type
f -name "*.elc" -delete` but it didn't help. 🤷
