[Freeciv-Dev] can_player_build_air_units_at_all

[Gregory Berkolaiko <Gregory.Berkolaiko@xxxxxxxxxxxx>]

Hi,

My air units AI seems to be working now (minor problems left to fix), but 
I need the above function so I can skip all air calculations if they are 
unnecessary.  I need your advice here.
As I see it there are several possibilities:
1. The ugly kludge I use: 
player_knows_improvement_tech(pplayer, B_AIRPORT)
2. Even worse: hardcoded check for technology with name Flight...
3. New variable in game.rtech
4. New technology flag: "Flying"

Probably the best solution would involve a mix of 3 and 4.  Please help me 
out here, I am not very experienced with all these 
flags/ruleset parsing/generalised techs things :((

Best,
G.
