I like and appreciate them too. (I was just figuring out what's going
on.. ;-))

Yes, I compared your list of dependencies with the "nice-to-have" list
suggested in nt/INSTALL.W64 and these are all there - in your
script. :-)

Thank you

We had an issue with a missing libgmp-10.dll on computers without MSYS2,
though. So Corwin added it as an additional dependency.  I read that
this library should not be strictily necessary for Emacs to run - there
should be some inbuild fallback method available.

I suspect on OUR MSYS systems the gmp library is present and then
configure is setting up our builds to expect this presence on all
machines..
