/**
   Test: V_case2_i   - Assignment of private data to shared data.
   Purpose:
         To check assignment of private data to shared data.
   Type: Positive.
   How : - Define a shared integer and a local integer variable.
         - Each thread assigns MYTHREAD to the local integer.
         - Sequentially, each thread assign its local integer to the shared
           integer and the others threads check the value of the shared integer
