The macro definition and expansion has to be changed.

Macro definition has to handle the formal parameter list, and this added 
code will execute only when a parameter list is present.

Macro expansion will have to deal with the actual parameter list, also 
only when such a macro is used. With proper separation of old and new 
macro handling (with/out parameters), the new code again only executes 
when new macros are used in the code.
