title: Why does my Mac OS X Xcode 4.2 project think I've set an OS X target lower than 10.3
body: <p>I get compile failures because "NSSegmentedControl" (which I use) is reported to be unavailable on OS X prior to 10.3.  Fine.. but I've set my project to 10.7 everywhere. Same issues with Clang and GCC.</p>
  
  <p>Is there a limitation to creating 32-bit OSX applications on Lion?</p>
