locate() + foreach_dimension() \rightarrow input in flex-scanner failed

qcc gives an error if foreach_dimension(){...} is called.

Workarounds include;

1. Use a (dummy) code block
2. Do not use a block with foreach_dimension() (for one-line blocks)

#ifndef DUMMY_CODE_BLOCK
#define DUMMY_CODE_BLOCK (0)
#endif

int main() {
  init_grid (N);

unused variable ‘point’ [-Wunused-variable]

  Point point = locate (0.5, 0.6);

#if DUMMY_CODE_BLOCK
  {}           
#endif

‘x’ undeclared (first use in this function)
‘y’ undeclared (first use in this function)
‘z’ undeclared (first use in this function)

  coord a = {x, y, z};
  foreach_dimension() {
      printf ("%g\n", a.x);
      a.x = 0;
  }
}
