Details:

No map can be wider than 32k tiles.
+verbose+
 struct tile {
-  int x, y; /* Cartesian (map) coordinates of the tile. */
-  int nat_x, nat_y; /* Native coordinates of the tile. */
+  u_int16_t x, y; /* Cartesian (map) coordinates of the tile. */
+  u_int16_t nat_x, nat_y; /* Native coordinates of the tile. */
-verbose-

these:
struct resource *resource;
struct terrain *terrain;
can also be decreased in size from 8 bytes on 64 bit platforms to 1 byte.
They can be an index in a table of resources, or terrains. What do you think?
