<ompts:testdescription>Test which checks the omp threadprivate directive by filling an array with random numbers in an parallelised region. Each thread generates one number of the array and saves this in a temporary threadprivate variable. In a second parallelised region the test controls, that the temporary variable contains still the former value by comparing it with the one in the array.</ompts:testdescription>

!of C version at 05042004

!The undeestanding is that sum0 and myvalue can be local static variables

!of the chk_omp_threadprivate function. There is no need to use common
