For an "unwind.h" header, other than the one included with Clang. :)

There's a patch floating around for Clang--that I wrote ;)--that fleshes Clang's built-in header out, so that it actually includes such important declarations as "struct _Unwind_Exception". I've attached it here for your convenience. (I wanted to commit it, but nobody's given me the go-ahead yet.)
