I just tried gretl 2017b, the gnuplot work fine.
Gnuplot's Windows "terminal" has come to depend on more (and more
recent) native Windows functionality, including that of d2d2.dll.
I recently updated our build of wgnuplot.exe, but I wasn't aware that
this new stuff would break Windows XP support. Maybe we should drop
back to an earlier gnuplot version.
