[omniORB] CORBA::Any_var

[Ken Feuerman]

What about making use of the TypeCode somehow?  Something along the lines of

CORBA::Any_var a;
CORBA::TypeCode_var tc = a->type();  // not sure if "TypeCode_var" is an 
official mapping?
if (tc->kind() == tk_null)
     cout << "The Any_var has not been initialized" << endl;
