I'm writing C in Visual Studio 2010. The compiler doesn't seem to want to let me use inline variable declarations. The following code produces an error:

unsigned int fibonacci_iterative(unsigned int n) {
 if (n == 0) {
  return 0;
 }
 if (n == 1) {
  return 1;
 }

 unsigned int prev_prev = 0; // error
 unsigned int prev = 1; // error
 unsigned int next = 0; // error
 for (int term_number = 0; term_number < n; term_number++) {
  unsigned int temp = prev_prev + prev;
  prev = next;
  prev_prev = prev;
  next = temp;
 }

 return next;
}

Error:

error C2143: syntax error : missing ';' before 'type'

error C2143: syntax error : missing ';' before 'type'

error C2143: syntax error : missing ';' before 'type'

Why is this happening? Is there a setting to make the compiler not so strict?
