Per Sven's idea, the gretl snapshots for Windows now contain

I would not particularly recommend replacing the gnuplot build
supplied with gretl with one from the gnuplot site, either on Windows or Mac.
We'll see about updating the gnuplot we package for Mac shortly.
The current macOS snapshot now includes gnuplot 5.2.6.
