[Bug c++/16019] New: Redundant warning `class X' only defines private constructors and has no friends

["amos at ilogix dot com" <gcc-bugzilla at gcc dot gnu dot org>]

The warning "`class X' only defines private constructors and has no friends" 
is redundant when using a typical singleton pattern implementation yet there 
is no way to turn it off.
In a project with few singletons it cause redundant "noise" in the compiler 
output.

example:
--------

class X
{
public:
   // get X singleton instance
   static X* instance();

private:
   // prevent direct initialization
   X();
};
