I confess that I am confused about what, precisely, you are asking for.
You are correct that standard C only allows arithmetic on pointers to
complete object types. But `void *` is not a pointer to a complete object
type, and so therefore pointer arithmetic on pointers of type `void *` is
illegal. So in that sense, Plan 9 C is already following C99.
