Mac OS/X Port data Model

[Gary Meyer]

I hope I'm answering your question here.  What Mike checked in is the ability to build universal binaries, which means both 32 bit and 64 bit binaries are built at the same time.  Mac OS X has the ability to make binaries (both executables, and object files, etc) with multiple "slices", meaning you can combine a 32 bot binary with a 64 bit binary into one Universal binary.  If I'm interpretting your question correctly, there is nothing that needs to be done to build both slices.
Gary.
