[Reduce-algebra-developers] Updating gnuplot

[Rainer S. <rai...@gm...>]

We are distributing gnuplot 4.6.0 (released 2012) as part of the Windows
snapshot. I believe we should upgrade to release 5.4(.10). The examples run OK;
I don't see anything critical in the in the manual section listing
the differences between versions 4 and 5.

Objections, anyone?
