New Revision: 65232

URL: http://llvm.org/viewvc/llvm-project?rev=65232&view=rev
Log:
Add test case to record a couple inconsistencies with GCC (found in <rdar://problem/6561076> [clang on Xcode] warning: cannot find protocol definition for 'OzzyP').

Removing the "cannot find protocol" warning is trivial if necessary (but I don't think it's the right thing to do).
