These are currently the only mingw-w64 packages that I don't have in the repo that are in AUR and not orphaned (as of Nov 26, 2013).
I am currently using a 1GB/30GB VM from digitalocean
Not all packages compile with 1GB of ram so I created a 512MB swap file.
Fedora and Opensuse both have a good mingw-w64 toolchain with plenty of packages.
