[omniORB] OmniORB wilth DLL

[Ulf Stoermer]

Okay, admittedly I read the first posting a bit carelessly.

But then, in this case the ORB_var is private, so there is no need
to export the symbol. The __declspec can also be used selectively
on individual class members, e.g.

class Object
{
private:
  CORBA::ORB_var orb;
public:
  void __declspec(dllexport) doWhatever();
  ...
} 

Cheers

Ulf
