I'm not sure we're talking about the same things here.
Pedro was mentioning src/newlib/* while Kevin asks for mingw32ce. Two
different worlds.
I have been looking into getting a generic exception handler to work for
mingw32ce, but haven't had any success yet. This is a requirement for
having any kind of exception handling - I am not very knowledgable about
the differences between g++ and SEH. But right now, I think neither can
work.
