9 // note: this program tests the inter-operability of different
10 // extended typeinfo systems. In this example, one class is
11 // identified using the default RTTI while the other uses a custom
12 // system based on the export key.
14 // As this program uses RTTI for one of the types, the test will fail
15 // on a system for which RTTI is not enabled or not existent.
