Two -getX()'s?

[donalson]

Marcus,

   I am having some compile trouble.  I have an object "mussel" (the
animals that grow in the intertidal zone) that has two procedures, -
(double) getX() and - (double) getY that return the X and Y coordinates
of the individual.  (I am implementing a continuous space model.)  The
problem is that the compiler/linker seems to be getting then confused
with -(int) getX() and - (int) getY() from gui.h.  Shouldn't it be able
to differentiate between procedures from different objects?  I can
change my procedure to something like getMusselX but I don't see why
there should be a problem this way.

gcc -c -g -O2 -Wall -Wno-import -Wno-protocol   -DAPPNAME=mussel   -DDLL
-I/Swarm-2.0/include Mussel.m
Mussel.m: In function `-[Mussel initializeMusselNeighbors]':
