> Two questions:
> 1. Is anybody using kaffe on a system that does not have
NCR MP-RAS have sigsetjmp/siglongjmp
> 2. Is anybody using kaffe on a system that does not support sigaction?
NCR MP-RAS have sigaction
> The reason I'm asking is because Pat wrote an optimized version of

The answer is: better kaffe
