[PATCH] Fix build on FreeBSD 12 (latest patch level)

[bsdtrhodes]

This patch should cleanly apply to the checkout directory. Next up, I'll look at launchd and/or libdispatch, but we'll see how much work they need. Also, I don't now why these "no new lines at end of file" appear, seems to be specific to git, at least on my system. Thoughts? Also, looks like the patch blows up in the paste - I'm new to github, if you want a diff emailed, let me know.
