Thanks so much for testing Dieter!

No.

I'm having trouble replicating this.  I see libgnutls-30.dll (and also
libgnutls-openssl-27.dll?) in both the -deps.zip and inside
with-native-compilation\emacs-28.0.91.zip

Any thoughts on what could be up here?

Hmm.  I've uploaded my key a few places (in addition to posting on
Savannah).  I can look for other places to publish it -- any
suggestions?

I don't think I quite understand this suggestion -- not a rejection.
Likely, you are wiser than I in the ways of GPG.

I'm fairly sure the binary release packages have never included
source.  I suspect the size difference is accounted for by omitting
-static while compiling.

Can you elaborate?  Is this a difference between my prior versions and
the current, between what Philliip was producing and what I've been
making, or somehow .. both?

Quite alright -- as I mentioned in the new thread[1] from today, I was
able to test the installing to a machine with a working msys (on path)
does enable native compilation to work, so I'm feeling a bit less
pressure on that score.  Don't get me wrong: I'll be very happy when
you are able to take a look.

No, I'm not expecting any differences between Windows 10 and Windows
11 that we'll notice WRT the packaging process we are using.   That's
not a super expert opinion, to be sure.  I can likely give the
installer a try under Windows 11 next week sometime.  I'll report back
directly in case of any supprises.
