Hmm. In that case, it's not an Xcode 4 problem. On my system, AR_EFMT1 is defined in /usr/include/ar.h, which is included at the top of archive_file.cpp, so I'm unclear why this identifier is allegedly undeclared on your system. Google turns up only one hit for "AR_EFMT1 undeclared" -- this thread. So this is not a general problem, and seems to be specific to something about your system. Is Xcode installed in a nonstandard location? Is there anything else unusual about your system that you can think of?
