multiple declarations for `setObjectCollection;'

[Rene Kongsgaard Jacobsen]

Hi.
During a compilation of our own swarm-model gcc gave me this error message:

ColonyObserverSwarm.m:135: warning: multiple declarations for method 
`setObjectCollection:'
/pack/swarm-961002/include/defobj.h:96: warning: using 
`-(void)setObjectCollection:(BOOL)objectCollection'
/pack/swarm-961002/include/space/Object2dDisplay.h:24: warning: also found 
`-setObjectCollection:objects'
ColonyObserverSwarm.m:135: warning: passing arg 1 of `setObjectCollection:' 
makes integer from pointer without a cast

 
As far as i can remember the ObjC standard declares that different messages 
with the same name MUST have exactly the same interface, so there seems to be a 
conflict between defobj and Object2dDisplay. The compiler does ofcourse choose 
the  wrong implementation, and returns the integer from pointer error. Is there 
any way i can specify what implementation the compiler shall use? I tried 
moving #import<space.h> to the top of the file, but that didn't seem to have 
any effect.
