Yep, he should be good to with just an update. I also modified the icon file, updated the frameworks, and made sure that CVS was set to preserve the binary status of those files (to avoid future corruption from Windows-user commits, like has happened in the past).
The changes in that thread don't really apply though. It's still only the 3.6.9 branch, the changes that apply to HEAD are going to have to wait. I don't have time to fix all of the problems that exist in HEAD right now in order to make sure it all works properly cross-platform (Linux had a ton of errors before, and still has a few issues that affect stability, and the Mac builds will need quite a few more code fixes before they are safe to use). The platform specific stuff, in either branch, is available to the project files but are part of any active builds, so changes related to those won't affect building in any way.
