iPhone Application build copies <Prefix_filename>.pch.gch

Question

I large (12 mb) Prefix.pch.gch file is being copied to my final iPhone application. It does not exist in the project and only shows up in the build log. It adds quite a bit to my otherwise small application size. Any suggestions for stopping xcode from copying it? Does anyone know what it is? I did a little research, and it looks like a cache file for a precompiled header, but I couldn't find anything as to why its 12 mb.

See my answer here for a possible cause. If that's it, it should be easy to fix.
