Well, this re-naming looks strange for me. I could understand if you had
a global exported empty_*ops which you could share and shrink the .data
size a bit. But this re-naming just looks useles, if you take into
account the breakage and the men-hours we spend to write e-mails to this
thread - really did not worth it. Or I miss something?
