        Cities under the size which requires an aqueduct can generally
feed themselves quite well.  If anyone has reasons why this is a poor fix,
please discuss them with me.

        I think it's a good idea to think about improvements like
 that, BUT your fix isn't complex enough.

 For example, a city that has little or no food surplus and is 
 using/ has available some sea squares will need a harbor to
 grow to a size where it needs an aqueduct.

 I think somewhere in the AI code there is a function like
 "city wants food to grow" (it is used somewhere in luxury rate/
 tax rate determination).

 Another thing to be careful about is 'dead locks' i.e.
 check that the rule for building an aqueduct isn't:
 if(pcity->size>6 && pcity->food_surplus>0)
        set_city_build(B_AQUEDUCT);
 Which would make the aqueduct wait for a harbor and the harbor
 wait for an aqueduct.
 The new parameter 'aqueductloss' should be considered, too,
 especially when devining the need to buy an aqueduct with money.
