Sorry Andrew, another one for you I think..

```
int inhcoords, bbox_ncols;
void bbox(float bb[][5], float *p) {
  int k = 0;
  for (; k != inhcoords; k++)
    bb[1][k] = k;
  for (int i; i; i++)
    for (int j = 0; j != bbox_ncols; j++) {
      k = 0;
      for (; k != inhcoords; k++) {
        bb[0][k] = p[i * j];
        if (bb[1][k])
          bb[1][k] = p[i * j];
      }
    }
}
void MapdescbboxTooBig(float bb[][5]) {
  float bbpts_0_0_0;
  bbox(bb, &bbpts_0_0_0);
}
```
