How does XCode propagate build settings to sub projects (or does it at all?)

Can someone succinctly explain how build settings propagate from the top level project down through referenced sub projects?

I've got an ios project I started under XCode 3. It has references to three open source libraries that include their own XCode projects - not all of them specify they can be built for ios, but they're in generic C so in reality they can.

Do I need to update each of the build settings in each sub project to match the enclosing projects?  I'm getting weird errors along the lines of 'file not found armv7' because the only architecture specified in the included project is armv6.  I'm getting errors about ignoring linking with libraries built during the same build pass - errors saying build settings for library don't match.

This is maddening - the same project built OK on XCode 3.
