/**
   Test: III_case1_i -- Qualifying an object as "shared shared"
   Purpose: To check that the qualifying an object as "shared shared" 
         through the usage of typedef is permitted. 
   Type: Positive
   How : - Define a new type shared_integer as being shared integer.
         - Declare a shared variable of type shared_integer.
         - Test the affinity to thread 0. 
         - Check that a specific value written into the variable by 
           thread 0 can be seen by all threads.
