Strange as I can load calc package in emacs. Indeed when I try to 
get information on this variable with C-h v, there is nothing.
I have a look on calc.el and I have the following lines (1428):

(defvar calc-aborted-prefix nil)
(defvar calc-start-time nil)
(defvar calc-command-flags)
(defvar calc-final-point-line)
(defvar calc-final-point-column)

Indeed, when I tried to use C-h v on the two first variable, it match.
But not for the following. The main difference is that the first two 
variable have the nil value and not the following.

I put a (require 'calc) in my .emacs. It is still not working.
I decide to put the following instruction in my .emacs :

(require 'calc) 
(defvar calc-command-flags nil)

Then it works ! 
It seems that there is problem of initialization of this variable.
Shouldn't this variable be initialized by default in calc ?

Thank you for your help.
