-/* Test the protected visibility when main is linked with moda and modb
- in that order:
- 1. Protected symbols, protected1, protected2 and protected3, defined
- in moda, are used in moda.
- 2. Protected symbol, protected3, defined in modb, are used in modb.
- 3. Symbol, protected1, defined in moda, is also used in main and modb.
- 4. Symbol, protected2, defined in main, is used in main.
- 5. Symbol, protected3, defined in moda, is also used in main.
