Since we can't directly use C++11 attributes, I've chosen BOOST_FALLTHROUGH to annotate intentional fallthroughs.
Thanks to @fosnola for spotting a missing break, which triggered this.
I've checked and found that none of the existing warnings are incorrect (other than those fixed a couple commits ago), but the main reason for disabling it is that one of the warnings is in Boost.Array which I can't do a lot about.
This now requires Boost to be installed by MacPorts. However, we could add the standard Homebrew path to the include path as well to support both.
This also requires SFML and its dependencies to be installed in /Library/Frameworks; it's unclear whether this is reasonable.
Code signing is completely disabled, and Zlib is now loaded as a tbd instead of a dylib. This will probably break for some older computers, but hopefully they can just use the Xcode 4 project instead.
Boost is forcing -mt suffixes on all its libraries. Whatever. We'll just roll with that.
This makes the script work both with and without the suffixes.
Using parentheses instead of braces silences the stupid narrowing warning, so yay.
Some of these warnings are probably not correct but I can fix them later
The code signing recommendations and the suggested plist updates were skipped.
The plist changes in particular appear to be unsupported in Xcode 4.
