I realize that, I just wasn't sure what components were associated with
those DLLs as of when the setup script was created.  I got it to build
locally (though Meld exits with "application requested runtime to terminate
in an unusual way" after it's installed.  On Appveyor it still fails with
"error: invalid command 'bdist_msi'" for some reason.  I tossed what I have
so far into https://gitlab.gnome.org/keeganwitt/meld/tree/meld-3-18-mingw.

On another topic: anybody else seeing this error when closing Meld built
with the AIO setup (it only happens when the prompt asking whether you want
to save the changes occurs)?
