The ifndef/define didn't protect against redeclaration? Huh. Maybe
I'm not thinking about this correctly, or the arch specific code is
doing something wonky ...
Regardless, assuming that it is necessary, I would prefer if we called
it auditsc.h instead of auditscm.h; the latter makes me think of
sockets and not syscalls.
