IIRC GCC/G++ already implements two-phase EH (that's what SEH basically
is in essence) according to

http://sourcery.mentor.com/public/cxx-abi/abi-eh.html

which states

"A two-phase exception-handling model is not strictly necessary to
implement C++ language semantics, but it does provide some benefits. For
example, the first phase allows an exception-handling mechanism to
dismiss an exception before stack unwinding begins, which allows
resumptive exception handling (correcting the exceptional condition and
resuming execution at the point where it was raised). While C++ does not
support resumptive exception handling, other languages do, and the
two-phase model allows C++ to coexist with those languages on the stack.
