help regarding pragma in CodeWariror...

Hi evryone...

      My power PC MPC566 supports
#pragma interrupt [SRR DAR DSISR fprs vrs enable nowarn]. on | off | 
reset
i am getting a warning that my function size is exceeding 256 bytes, 
and to supress this warning i have to pass 'nowarn' option to the 
pragma.
Can anyone suggest me how to pass this option? Any kind of help is 
welcome.

-regards
Rajesh
