I suppose we could. gcc has a neater way to deal with the problem:
#ifdef __GNUC__ 
#define ARG_UNUSED __attribute__ ((__unused__))
#else
#define ARG_UNUSED
#endif

and then one can use:
void xx(int i ARG_UNUSED){}

but then, it is just as easy not too worry about it and disable the warning
related to unused argument using a compiler option.
