[omniORB] dump an IDL tree with value types

[Laurent Pautet]

This IDL file:

valuetype A long;
valuetype B {
   public A X;
};

is not properly dumped by omniorb:

valuetype A long;
valuetype B {
  public value box X;
};

The scoped name A is dumped as "value box". This bug can be reproduced
for a scoped name designating any value type.
