cscope-minor-mode not enabled for C in emacs 25

[stefan . puiu]

Hi, 

I've asked this also on Emacs stackexchange 
(https://emacs.stackexchange.com/questions/38822/cscope-minor-mode-not-enabled-for-c-in-emacs-25),
 trying my luck here...

I'm using Emacs 25 on Ubuntu 16.04 and all is mostly well, except that there's 
one difference between this version and 24 - on Emacs 24, any C/C++ file (*.c 
or *.cpp) I would open, cscope-minor-mode would be enabled. This isn't the case 
anymore on 25 (I've checked with 'C-h m'), so I have to type 'M-x 
cscope-minor-mode' on each new file I open, which is quite annoying. I'm using 
xcscope-el that ships with this version of Ubuntu (1.1-1, says dpkg output). 
Any idea what could be happening here? A pointer to where to start looking 
would be very helpful. 

Thanks in advance,
Stefan.
