My plan is to introduce a parameter warmap.sea_to_land which will be
returned instead of -3.  The default value would be MAXCOST (thus
forbidding such movement).  But if warmap is generated for , say, a
transport carrying engineer to build a new city, the cost would be
SINGLE_MOVE.
However the user would have to insure that he doesn't process a land
tile.

Another way is to always return SINGLE_MOVE and to amend
warmap_process_tile to check for the sanity of the proposed tile.

However the best way would be to split move_cost into sea and land costs
and set land-to-anything sea_move_cost to be MAXCOST, thus avoiding the
need to check for sane tile...

Suggestions and constructive criticism are welcome.
