I'm happy to make the change.  But I could do with some help.  BTW, I'm not
using any functions here.  Only the u_context accessing via the siginfo
parameter passed into a signal handler as in

void    (*__sa_sigaction)(int, struct __siginfo *, void *);

So if you know how to get the register state from that on OpenBSD I'd like
to know.  Otherwise condescend to someone else, ok?
