AFAIK there are no special restrictions because of high winds ..... however .... major airports will suffer reduced capacity with high winds down the runway axis. Normally they will separate similar aircraft by 2.5 to 3nm on final approach. Lets say you fly 180 kts to 8 nm final then 160 to 4 then reduce to final approach speed. Flying 180 kts in still wind will take you 1 minute to fly the 3 nm you are behind he preceding aicraft, with a 60 kt headwind your groundspeed will be 120 kts, so the 3 nm will take 1.5 minutes to fly. Hence fewer movements possible.
