I dare to decline ;-)

Kylix implements the same SEH as is used in Delphi, without assistence of the
OS, and FPC most probably does the same for non-Windows platforms. It's only a
matter of compatibility that Delphi uses the Windows SEH model and support, and
only the use of exception objects is a Delphi or OPL internal thing. We could
name it SEOH ;-)

SEH is not a property of OS's in general, instead it's a language feature.
Exceptions or, as formerly named: Interrupts, are a matter of the OS. The
Handling of exceptions is another topic, and it's only for convenience that
Windows implements SEH features for cross-language usage.
