Why do you use concatenation? Do you know what it means? 
(see 'info cpp Macros Concatenation')

Just remove the concatenation (##) "operator" and it should work (but you don't 
show a complete example and there might be other issues).

PS: What is NOT_ACCEL_MOVE and what does it have to do with TEST_SUB_VIEWS?
