LLVM still assumes SJLJ or DW2 exception handling, and does not bother to
check this at configure time. Well, the reason is that someone hasn't
written a simple test for that and implemented the proper #ifdef stuff.
So you can just use this patch:
http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20120924/151822.html
Problem with the patch is that it also affects non-seh 64-bit GCC's, so
only use it when you are building with GCC 4.8+ with seh.
Cheers,
Ruben
