That warning message appears justified, because there's a bug in the 
plot script (at least the one you showed).

It doesn't really make much sense to request ticks on the y2 axis, but 
nothing else: no data on the y2 axis itself, nor any stated relation 
between y1 and y2 axis,

FWIW, I suspect adding

	set link y2

should reinstate the behaviour of older versions of gnuplot for you. 
OTOH, if you were actually going to use the second y axis, there should 
be 'axis x1y2' options on the applicable datasets (Sys, Dia).
