I think the intent there was just that the structure member names match the
names of the entry point symbols in the audit library.  The reason the API
for those functions uses a different name for each CPU is that the
signature and what you need to know to implement it also differ for each
CPU.  It is not something that is ever used generically like sigcontext and
jmp_buf are.
