I expected as much.

Makes sense.   How can I help?

One other thing I found is that -installer.exe requires libgmp-10.dll
but either ..
1. only when Emacs is build --with-native-compilation or else
2. only when -static isn't present
I have no idea which, so far.

Looking forward to reviewing/researching further after work today.

As Dieter said (in the other thread) -- I too would very much
appreciate any tips you can share WRT your preferred/personal approach
to crafting the windows binaries/zips.  Thanks so much for that offer.
