Yeah that's right.

Ok.

which are forced to SJLJ is that right?

Those are pretty rare aren't they?

So the question "if I build a version using mingw's recent 4.4.0
release [dwarf-2]" will it work with cross-compiled binaries that gem
developers provide, and I think the answer is yes, because we don't
care all that much about exceptions crossing dll boundaries.  I guess?

Any thoughts on this one?
