linux-2.5.45 appears to have replaced dst_entry.pmtu with dst_entry.metrics[RTAX_PMTU] and created a helper function dst_pmtu(struct dst_entry*), presumably to simplify future changes like this one. Now the files compile. That is as much as I have tested.
I am not currently familiar with this code, so I could easily have misunderstood something in this patch.
