McPherson strut designs can be seen on 84-87 (Torsion bar) Hondas, and I believe Ford Escorts, at least pre-'92.
Basically, it means that the strut is designed to control multi-axial motion, rather than just up/down (suspension's normal working range).
IOW, it replaces the "upper control arm" in dual a-arm setups.

It can also be seen on most GM midsize cars, pre-OBD-2, at least. (Grand Prix, Grand Am, Bonneville, etc.)
The image at the top of that link is exactly what a '94 Grand Prix has.
