If you want a better answer, you should be able to grab gcc from the apple cvs server and grep relax | grep -i 'apple local' and get hits on all the relevant code. Roughly, think about field offsets and structures types...

While it may be OK to tell us to read the source, Apple should really document these options for its users. Perhaps it did, but I couldn't find it.
