Hi,
I'm using GNU Emacs version 21.2.1 and  I have a problem with  shortcut
for uncomment-region function in c++-mode, in my .emacs file I have:

;; shorcut for comment region
(global-unset-key "\C-c\C-c")
(global-set-key  "\C-c\C-c" 'comment-region)

;; shortcut for uncomment region
(global-unset-key "\C-c\C-u")
(global-set-key "\C-c\C-u" 'uncomment-region)


Now, what is going wrong. Shortcut for comment region is working fine,
but for uncomment region isn't. When I edit a C/C++ source file, I'm in
c++-mode, and then when I try to uncomment a commented region with shortcut \C-c\C-u,
I receive this message in echo area: No containing preprocessor conditional

So, could you help me with it? Does anybody know how to do correctly
what I want?
Thanks for any suggestions, Dave
