Great it works perfectly, now I have to understand how the heck I can
make "gtags" understand c++ code...
But that's another story...

Instead, is not possible somehow that when I say

public class X : public Y {

}

I get all the needed declarations automatically.
I didn't find anything useful in CEDET about that, but maybe there is something...
