Hi Andy.  Very sorry for the late reply, it's been a few weeks since I
caught up with the list.

I just rebuilt with the latest git and it seems to be working.  I've
been using this as a test:

(call/cc (lambda (k) (sigaction SIGINT (lambda (_) (k))) (let loop () (loop))))

And then interrupting with ^C.  I also tried using SIGQUIT and ^\ with
the same successful effect, so it looks like it works.

Many thanks!
