Date: Mon, 8 May 2006 14:19:30 -0700 From: Bob Ippolito Subject: SDL trunk (r2346) and Mac OS X The current state of the trunk doesn't quite compile on Mac OS X, I've attached a series of patches that gets it to compile and kills a few warnings. sdl-trunk-r2346-dlcompat-warnings.diff: The dlcompat thing is just loaded with incorrect type signatures .. some of them have changed since 10.2 and others are just flat wrong. This puts it in sync with the latest headers. People on 10.2 will get the warnings instead of people with new kits.
