[Orgmode] bug: keymap interference with calc

[Thomas Baumann]

Hi Carsten and others

there seems to be an interference with the way org-mode captures 
DEL. This happens with emacs 22.0.96 strated with emacs -Q

Load org, visit an org-buffer, load and start calc,
in the calc buffer backspace is bound to

DEL (translated from <backspace>) runs the command delete-backward-char
  which is an interactive built-in function in `C source code'.
It is bound to DEL.
(delete-backward-char n &optional killflag)

...

which causes an error in calc because there DEL should be bound to

DEL (translated from <backspace>) runs the command calc-pop
  which is an interactive compiled Lisp function in `calc.el'.
It is bound to DEL, C-d.
(calc-pop n)

...

If calc is started _before_ org-mode everything is ok. This behaviour
is present in all versions since 4.57 and also in emacs-cvs.

Best wishes
Thomas
