Hmm. In principle we could replace strcoll() with a wrapper around
this, using a src/port/ module. The real problem with this is that it's
new in Leopard, and thus not even adequately portable within the OSX
world.

I just checked sort(1) on 10.5.2, and it seems to still behave the same
as before, so nope they didn't change it.
