     A name for a macro parameter.  The macro is equivalent to

	#define RF_ARG16(p0, p1, p2, p3, p4, p5, p6, p7, p8, p9, \
	                 p10, p11, p12, p13, p14, p15, ...) p15

or to

	#define RF_ARG16(a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,...) p

     In any guise, it looks like a symptom of macro overreach if
not outright macro abuse.
