[NTLK] Einstein and Xcode 4, problems with Cocoa graphics calls, HELP NEEDED.

[Steven Frank]

I just updated from Subversion to try it in Xcode 4.5 which was just
released (GM) yesterday.  Builds and runs fine, but has some
deprecation warnings, because the 10.6 SDK is no longer included.

Matthias, if you want, I can check in fixes for these warnings (I
fixed them locally), but it will mean the minimum system requirement
for Mac OS X jumps to 10.7.
