Without looking at the patent, I would hazard the guess that it is about Win32 Structured Exception Handling (SEH): http://www.microsoft.com/msj/0197/exception/exception.aspx (The linked-to mail from the GCC mailing list seems to confirm this.) SEH is quite important in Windoze-land. Ranjit. -- Ranjit Mathew Email: rmathew AT gmail DOT com Bangalore, INDIA. Web: http://ranjitmathew.hostingzero.com/
