Actually, this holy war can be bypassed, without sacrificing Emacs
correctly working on a console.  What the console should send for that
is the <Backspace> function key.  Emacs already takes care of
converting this to DEL.  The following is from a native Windows build
of Emacs 23 running under -nw in the Windows standard "Command Prompt"
window:

  DEL (translated from <backspace>) runs the command delete-backward-char

This message was caused by typing "C-h c" and then pressing the
backspace key.
