As far as I'm aware, the game doesn't actually use that function - it's just
part of the LUA library. So we've got two options - either provide a dummy
prototype so it'll compile okay, or directly modify the LUA code to comment
out the call. I would lean towards the former, so as to keep the LUA code as
pristine as possible. Although changing it in the code means it would be
fixed for all other systems as well.
