To work around the narrow API in the comparison function we have to either

its a bit ugly in C++98, but you can give std::sort a random object with
operator () to compare with.

So we could just wrap the object with a class that has a suitableoperator? I like that much more than mucking around with globalvariables. Let me give that a whirl.
