Well, essentially you have two choices:

1) Replace the machine with an architecture which is known to work.

2) Fix gcc so that the example program works.

Neither are terribly good options, I'm afraid.

Can you use gcc 3 on your platform? That might be worth a go. But 
probably a bit of a scary option.

This holds for alpha as well.

C++ on OpenBSD isn't terribly good. It works great on the common 
platforms in single threaded processes, but when you use 
multi-threading or a uncommon (64 bit?) platform, it has big problems. 
I don't think the OpenBSD team are terribly interested in fixing this 
-- most of their stuff in is C anyway.
