Wasn't Cocoa available for exactly those four platforms as well?

No Cocoa was not available on those platform. OpenStep was running on NeXT OS, and was available from NeXT on the Windows platform. NeXT and Sun worked on getting OpenStep running on Solaris but Sun did drop the ball and switched direction by going with Java. OpenStep was never available on HP-UX, only WebObjects and PDO were truly cross platform before the switch to Java. PDO=Portable Distributed Objects which was an alternative to Corba back when Corba was such a big trends.

Odd, Apple lists patches for OpenStep on both Solaris and HP-UX: http://support.apple.com/kb/TA45376?viewlocale=en_US

I think the Apple doc is slightly inaccurate: the OpenStep part which include a graphic user interface was not available on HP-UX but the non graphic part: WebObjects, Enterprise Objects Framework, and Portable Distributed Objects was available. Looks like Wikipedia has avoid history of OpenStep: http://en.wikipedia.org/wiki/OpenStep
