/* We want dbx, pcs and libexc to be able to tell the new
 * obj struct from the old.  Therefore, since the old one
 * has a pointer in the first 4 bytes, we ensure that the
 * first 4 bytes of the new one cannot be an address.
 * First and foremost, this is accomplished by setting
 * the sign bit, since that indicates kernel space.  I believe
 * that any application will have to know that it is in
 * 64 bit mode before it gets this far.
