Review comment:
Good catch, thanks. I do not have a Solaris dev environment, but there
is a service I can use to test R package building on Solaris, and this fixed
the previous compile error on it. Because of all sorts of other issues, I
haven't managed to get a full successful build yet (I'm up to 50% at the
latest), so I haven't gotten to the point of seeing if the code actually works.
