We use interitance quite heavily in our app and inevitably we will reuse the
same class variable names. But redefinition is allowed with inheritance in IDL.
Under jacorb 1.4 this worked fine.  Under 2.2 it is failing to compile.  Sample
code:

interface A
{
	const string NAME = "interface_A";
};
interface B : A
{
	const string NAME = "interface_B";
};

This code above compiles under 1.4 and TAO but fails under 2.2 with message:
