Easy:
You have to insert your exception handling routine at the linked list
of exception routines. Just insert it at fs:0, and in the 'next' field
put the old value in fs:0.
For the details see 'Microsoft Systems Journal', january I think. There
Matt pietreck explains how to do it.

You will have to write the exception handler catching routine. When an
exception happens, the system goes into that list at fs:0, and will call
the routine you specified. Microsoft's one is called exception_handler3
(or something similar). If the code uses Microsoft's exception handler,
you will get an undefined reference to that routine.
Again, I recommend to all people interested to read Microsoft Systems
Journal. I hope I got the exact month OK, but I could be wrong by
+ or - one month... typical programmer error!

To see an implementation of structured exception handler look at
the code
seh.c
in the lcc-win32 distribution.
It is binary compatible with MSVC.
