One last bit of information - which I got second hand, but hopefully
accurate. I think that the GCC team is on its way to generating the
unwinding info in that format, rather than the usual DWARF-based
eh_frame/debug_frame. So the Microsoft format should become the default
even for code generated by GCC... So eventually, I think we are going
to need to add an unwinder for that, even for GCC code.
