LLVM is getting better support for SJLJ exception handling. This would
get us to the same point GCC is at.

I think the bigger problem is lack of documentation on SEH and the
runtime support Windows provides for it. There has even been some
mailing list threads about it on LLVMDev recently... I think the best
solution will be to use Dwarf on Windows eventually as well (which
also seems to be the route GCC is going).

I'm not sure how Walter figured these things out ?
