How to get rid of this error?

While compiling the following function prototype of my header file I am getting an error as "extraneous old-style parameter list".

extern FUNC(Std_ReturnType, RTE_PUBLIC_CODE)  code_test(OUT P2VAR(PmpMngrCmd_T, AUTOMATIC, RTE_APPL_DATA)PmpMngrCmd);

where code_test is my function name and PmpMngrCmd in the function arguement while all other variables are very specific to a compiler, so for error free compilation in LCC I have defined them as empty macros like

#define FUNC(Std_ReturnType, RTE_PUBLIC_CODE)
#define P2VAR(PmpMngrCmd_T, AUTOMATIC, RTE_APPL_DATA) 
#define OUT

Pls help
