I think when the newest version come out you will be able to compile it because it's being made with the latest version of the devkit
I've actually decided I won't be releasing the source (I apologize for changing my stance on that. I originally thought the source for the new version was under the same license as the source for the previous one, but when I found out it wasn't I decided it would be best not to release the source so that it doesn't end up being completely copied into a backup loader).
Since I won't be releasing the source for the next version, I figured the least I can do is fix up the old sources to compile on newer versions of devkitpro:
