/* 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.
