Yeah, that's where I copied it from. :-) It works on Darwin because so far
OS_VERSION has always been something like "5.2" or "6.8". But if it's
"1.6.1" instead, make gets annoyed because that's a string, not a number
(since it has two decimal points).

But changing it there would probably still be good in case Apple starts
using weirder version numbers in the future.
