C Instrumentation Framework

I think that this is rather seldom case when somebody will want to match exactly some macro parameter names. Most likely one will need ability to reference some macro parameter by name specified. Thus:

#define A(a) ...

will be matched with the given pointcut:

define (A(arg))

but in corresponding advice one can refer to the first macro parameter as:

{
  arg + 1;
}

This feature request just serves as notification that macro parameter names won't be matched any more. The ability to refer to macro parameters is considered in #363.
