Date: Wed, 7 May 2008 21:48:10 +0200 From: Christian Walther Subject: SDL 1.3 Xcode projects Here are my promised updates to the Xcode projects. They work as far as I'm using them, but I have not tested them thoroughly, and there may still be some cruft left. In particular, I haven't checked whether the frameworks still work on older versions of Mac OS X (are we still targeting 10.2?), and whether Altivec/SSE optimizations are properly done. Of note: I incremented the framework version to B to enable SDL 1.2 and 1.3 to coexist in a single framework. Let me know if you see any problems. Greetings Christian
