Indeed, no significant difference.

During compilation, (eval-and-compile E) will be treated (i.e. compiled)
just like E, except that E is evaluated along the way (so the
definitions present in E are available during compilation).

They are. It's for `eval-when-compile` that they aren't.
> But are the _defmacro_ forms evaluated during compilation?
The defmacro forms are always evaluated (and byte-compiled) during
compilation (as if they were implicitly wrapped inside an
eval-and-compile).

Yes.
