According to this, it looks like it just starts the first "emacs"
found in the path.

https://github.com/jwiegley/emacs-async/blob/master/async.el#L287

But then, when I tested this, I didn't change PATH so I think async
should have run my /usr/bin/emacs, which is 24.3.

Another theory is that some .elc in your local ~/.emacs.d/elpa would
have to be recompiled.  But that's a use case we should support through
(cl-old-struct-mode 1), so I'd like to fix that.
