And your point is... ? Libjava does this for dwarf2 EH on Linux.

Exactly.
Incidentally, I would be willing to review and incorporate pieces
of this into gcc.
I can't promise anything about "__except" or "__leave" (indeed, I
suspect that they _won't_ be incorporated), but we can at least talk
about including SEH for general exception handling. At minimum you'd
be able to use catch(...) instead of "__except" in C++.

The runtime libraries can't handle both at once.
