annoying warning: class Foo only defines private ctor/dtor

[Yotam Medini]

Suggestion:

Using a class as a namespace-like wrapper should be legitimate.
I suggest to add a condition for issuing warnings:
  warning: `class Foo' only defines a private destructor and has no friends
  warning: `class Foo' only defines private constructors and has no friends
that the class also does not have public static methods.
The warning should then be modified to:
  warning: `class Foo' only defines a private destructor 
            and has no friends or static public members.
  warning: `class Foo' only defines private constructors
            and has no friends or static public members.

Example:
------------------------------------------------------------------------
telaviv:1547> cat NmSpC.cc; g++ -v; g++ -c NmSpC.cc 
class NmSpC
{
 public:
   static int  magic();
 private:
   NmSpC();
   NmSpC(const NmSpC&);
   ~NmSpC();
};

NmSpC::magic() {return 7;}
