Coming over the marker 27L at ORD on a visual approach I commented on strong x-wind at alt and the large crab we had in. Winds were 190/46 and questioned why we don't use 22L/R anymore. AT 750 feet we received an aural warning with a too low gear. We were at flaps 2 and 170. I then called for gear and flaps [and] landed normal.  We should have gone around at the aural warning and even though the landing was normal it was not the SOP. Looking back on it we must have also missed the 1;000 feet call out. If not we would have seen the abnormal configuration.
Cleared for visual approach about 20 nm from runway. Wind strong out of south at 42 to 48 knots. Severe clear; excellent visibility. Monitored Pilot Flying (PF); handling crosswind. Reached GPWS RA without realizing gear was not down and flaps at 2. Should have told PF to go around at that point but for unknown reasons; on command put gear down and flaps full. Approach was otherwise stabilized. Landing was normal.
A320 flight crew reported being alerted at 750 feet AGL that gear and flaps were not in landing configuration. Flight crew continued to an uneventful landing after properly positioning flaps and gear.
