Turns out that I fixed it for an update build, but not a clean build.   
There was one sort() call missing in the interface parser script.

Now the structures in player_interfaces.h are defined in strict order  
with their interface numbers.  This allows any interface to use  
structures defined by a lower-numbered interface.  Not a use case that  
I've thought very much about, and I doubt that the current scheme is  
very general or intuitive.  But it will work for now, in that it  
solves the use of camera structures by the stereo interface.
