Yes, we should fix this.

+typedef uintptr_t _Unwind_Word;
+typedef intptr_t _Unwind_Sword;
+typedef uintptr_t _Unwind_Ptr;
+typedef uintptr_t _Unwind_Internal_Ptr;
+typedef uint64_t _Unwind_Exception_Class;

It is a pity we have to define these, but I see that gcc's libsup++
still uses it :-(

LGTM, since it is a nop for users that already have an unwind.h setup.

Cheers,
Rafael
