I think that's the reason why HarfBuzz doesn't work for you:
libglib-2.0-0.dll is its dependency, but it wasn't found by the
system.  If it is not installed by the installer you used, I suggest
to report a separate bug about this problem.

I didn't know the snapshots are broken in this way when I suggested to
use them, sorry about that.

I think it's the same problem: the Glib DLLs are not in the package.
(You should be able to install them from the MSYS2 site, but at this
point I hesitate to recommend you to do that, as that might require
some time and effort on your part, and the snapshots on alpha.gnu.org
need to be fixed anyway.)

Phillip, would you please look into this?
