Yow, yeah these have been broken for a while now, build 188 (Jan 8th 2018) does seem to be the last good build. The weird thing is, I have a local MSYS2 installation and I can create Windows bundles that work just fine. So I'm not sure what the difference is other than my MSYS2 installation being more up-to-date than AppVeyor's. @achadwick any ideas? I saw there were a few commits to Styrene around the time it broke, but like I said my own MSYS2 is working. Maybe we just need to wait for AppVeyor to update the build images to new versions of MSYS2?

Weird: there should be a pacman -Syu in the build, so AppVeyor's build should be OK.

I'm chasing some oddities with recent Py3 fixes on MSYS right now, but I'll try to see what's up.

EDIT: and now Travis is barfing out with Swig errors too. Oh my.

I setup my own appveyor and tried various build images (2015, 2017, 2017 preview) and they are all broken in this same way. The build scripts do not upgrade or even update the cache, probably for good reason-- I tried inserting a pacman -Sy into the appveyor script (just so I could install a new package) and it seemed to trigger a massive upgrade that killed the build.

I just tried the latest alpha windows build and it appears to be fixed.
