bother to `optimize' the maxpop case, and it drops the weird food
limit computation for opt_NOFOOD, which didn't limited for any
reasonable game parameters.
(total_work): New parameter maxpop. Callers changed.
(newe, prod): Use total_work(). Old code failed to limit military
workers, thus didn't match the update.
(do_feed): Simplify.
even when option ROLLOVER_AVAIL was off. Previous revision correctly
limits rollover to rollover_avail_max, but missed the limiting after
rollover. Fix.
arrays instead of copies made by getvec(). This is safe, because the
old code made single copies and always flushed them back into the unit
structures. Else make copies by hand, not with getvec.
(starv_sects): Replace getvec() by direct, read-only item access.
(upd_buildeff, enlist, materials_charge, materials_cost, produce,
grow_people, growfood, trunc_people, do_feed, feed_people): Change
argument type to match uncopied item arrays.
(growfood): Obey ITEM_MAX.
instead of declaring them all over the place. This uncovered type
errors:
(s_p_etu, adj_update): Defined long, sometimes declared int. Kills
big endian machines where sizeof(long) != sizeof(int). Change to
int.
(set_option, delete_option, optstrset, intset, floatset, doubleset,
longset, optionset, optiondel, worldxset): Change linkage to static.
