   I've implemented Windows SEH-style exception handling (try / except /   
   finally) using C setjmp and longjmp, and I'm sure I'm not alone. C++ EH   
   can be built on top of that.   
      
   It's not particularly pretty, but it's portable in so far as setjmp and   
   longjmp are portable, if you e.g. discard register attributes for locals   
   etc.
