[libunwind] Re: compile error sc_rbs_base

Robert,

Sorry for not responding sooner.  It appears that somehow I got
unsubscribed from libunwind and hence didn't see your mail until
now... ;-(

Well, that's not a bad way of fixing the problem.  I'll see if I can
put some backwards compatibility in, so this problem doesn't show
