   First, I get:

   So it looks like things are not good. This is a checkout of a few minutes ago
 along the 3.0 branch.

   FYI, unwind-dw2-fde.o and unwind-sjlj.o give the same error, and all three
 also give the same error in the various {soft-float, single, el, mips3}
 variations.
 
                                                                         -Craig
