/**
-*** This file constructs type information for constant entities.
-***
-*** It constructs the information for a class type with a dispatch
-*** table. The class has a field a, and two methods f and g. The
-*** class is represented by a class type with two entities for the
-*** field a and the reference to the dispatch table. This reference
-*** is a constant entity. Ther dispatch table is also represented
-*** by a class type that contains the two methods. There is one entity
-*** of the dispatch table which is constant.
-***
-*** Further the example shows the representation of a constant global
-*** array.
-***
-*** class C {
-*** int a;
-*** void f();
-*** void g(int);
-*** }
-*** int[4] arre = (7, 2, 13, 92);
