[omniORB] Warnings regarding copy ctors with new gcc

[Matej Kenda]

Hi,

I have noticed that newer versions of g++ (3.3.1 on SUSE9 or 3.3.2 on
Fedora 1) issue warnings about explicit initialisation of base classes
when including headers of omniORB 4.0.3.

I have checked the headers, but I'm not sure what's the problem or
whether I should do anything to remove this warning.

I have copied relevant portions of header files and the warning messages
to the end of this e-mail.

Regards,

Matej

omniServant.h:

class omniServant {
protected:
  inline omniServant() {}
  inline omniServant(const omniServant&) {}
  inline omniServant& operator = (const omniServant&) { return *this; }
...

----
poa.h:

 class ServantBase : public virtual omniServant {
  public:
    virtual ~ServantBase();

...
  protected:
    inline ServantBase() {}
    inline ServantBase(const ServantBase&) {}
    inline ServantBase& operator = (const ServantBase&) { return *this;
}
