Cool, thanks. We can probably assume that if it compiles, it works fine.

Peter mentioned to me that _setjmp is supported on Solaris but not on very
old Solaris (like, 2.5). Question is, are there any supported
systems that don't support _setjmp at all. We believe that, if a system
does support _setjmp, it will do the right thing.
