I don't think this is by design. It seems a bug nobody noticed before
because people often do include dwarf.h also. But nothing else
explicitly needs the dwarf.h constants. It would probably not break
anything to explicitly include dwarf.h in libdw.h, but it seems better
to just define this constant explicitly in libdw.h as the attached
patch does. Does that make sense to you?
