So, if anyone else is interested / doesn't already know, if you 
encounter AUE_NULL errors compiling
rather than go and removing AUE_NULL from the system source (which works 
too), you can just add

#include <bsm/audit_kevents.h>

That's where AUE_NULL is defined.
You'd think they would have included that in the macro then, eh?
