Pretty sure all of this stems from 61c2183a440. I dropped using pactree 
and used pacman directly to determine dependencies. I also exclude glib2 
as a dependency hence the problem. If I include this, we go back to 
getting python and half the of msys2 included in the download bundle.

I guess for Emacs-27 I should just include glib2 and be exclude so of 
its dependencies (gettext and python probably). The question is whether 
to do this for Emacs-27.1 or 27.2.


For Emacs-28, I think I need a better dependency mechanism than looking 
at msys2, perhaps based around the shell script that was sent earlier, 
or an automated (or horror manual) use of dependency walker.
