I deeply regret the confusion I caused by pushing the "Send" when I 
meant to push "Write" to start a new, unrelated, message.  My updated 
re-send, as you probably have figured out by now, is more coherent.

OF_CPU is defined in the board-specific header file, e.g. 
configs/MPC8360EMDS.h, pulled in by config.h.  Since I am missing the 
#include <config.h> in the two files being discussed, OF_CPU is 
undefined and the string concatenation trick makes it silently disappear.

Best regards,
