OpenBSD seems to have forked at 3.4. FreeBSD appears to still be pulling
from upstream and it looks like FreeBSD 11 will have 4.7.4.

Neat. I suppose I've never read _arguments's docs that far down. Updated
patch below. I didn't make a set for -D, -J, or -h as OpenBSD doesn't
have them and (-* *) works.
