Hi,
I have a strange error which I don't know how to interprete.
I changed the RadioCountToLeds to use the CC2420ActiveMessageC.nc
directly and it works. Then I created another copy of
CC2420ActiveMessageC as CC2420ActiveMessageMineC and try to use it in
RadioCountToLeds. Even though I didn't change anything except the
configuration name, I can compile the code but I got following
infamous fan-out warning (I noticed that the size of ROM is greater
from when I used CC2420ActiveMessageC, sizes of RAM are the same in
both cases):

Could anyone help me know what the problem was and how to get rid of
these warnings.
Thanks,
