Which bug?

It looks so. Vasc is on daily at irc. Vasc has sent a mail to all
maintainers suggesting some names. No responses (this was 4 days
ago). So it looks like I have to choose but I'm highly unsure.

For each position track the amount of fuel available. The code should
honors this:

      case AIR_MOVING:
      case HELI_MOVING:
        if (warmap.cost[x1][y1] <= warmap.cost[x][y])
          continue; /* No need for all the calculations */
+       if(fuel_available<=0)
+         continue;

In addition to the current 8 possible choices ( adjc_dir_iterate(x, y,
x1, y1, dir) ) add a new one which refuels the plane and increment the
cost by one turn.

No. I won't allow such change just to get a better algorithm.

No. The railroad isn't the problem. You just take the number of
railroad steps as a part of the cost.
