Compiler Error C3013

'clause' : clause may only appear once on OpenMP 'directive' directive

A clause appeared twice on the same directive. Delete one occurrence of the clause.

The following sample generates C3013:

// C3013.cpp
// compile with: /openmp
int main() {
   int a, b, c, x, y, z;

   #pragma omp parallel shared(a,b,c) private(x)

   #pragma omp for nowait private(x) nowait   // C3013
   // The previous line generates C3013, with two nowait clauses
   // try the following line instead:
   // #pragma omp for nowait private(x)
   for (a = 0 ; a < 10 ; ++a) {
   }
}
