CORBA23 — Problem with C++ language mapping for OBV

Summary: 1. The following IDL cannot be translated into C++ code by an IDL
compiler for a C++ environment that does not support namespaces:

// IDL
module M {
struct S

;

interface I

;

value V supports A {
};
};

The reason for this is that module M maps to a C++ class when namespaces
are not available, and you end up with the following definition loop:

POA_M::I must be defined before M::V, since M::V inherits from it
M must be defined before POA_M, because POA_M::I depends on M::S
but defining M also defines M::V
