Here is the code : ( unit.c in your_freeciv_dir/common/unit.c )

int unit_can_help_build_wonder(struct unit *punit, struct city *pcity)
{
  return unit_flag(punit->type, F_CARAVAN) &&
    is_tiles_adjacent(punit->x, punit->y, pcity->x, pcity->y) &&
    punit->owner==pcity->owner && !pcity->is_building_unit  &&
    is_wonder(pcity->currently_building) &&   
    (pcity->shield_stock < improvement_value(pcity->currently_building));
}

  You have to use a unit with a flag F_CARAVAN. This unit has to be
adjacent to the city it wants to help. You have to own the city. The
building is the city has to be a wonder. You can't add more shields that
the amount necessary to complete the wonder. I don't recall any other
limitations to help build a wonder in a town with caravans.
