Is there some instructions for adding SSE4.1 support to XCode 3.1.x projects?  

See "Programming SSE in C" in the AlitVec/SSE Migration Guide

Also, what defines should be used to compile SSE4 intrinsics?

Add -msse3 to Other C Flags.

But before you go to all the trouble, read Mac OS X Manual Page For SSE4 and see what higher-level frameworks Apple has already built, tuned, and optimized for portability across the many chipsets available in Macs.

And do read http://www.macresearch.org/how_to_properly_use_sse3_and_ssse3_and_future_intel_vector_extensions_0 for the right approach for building projects for multiple chipsets.
