I think so too. Those old PC's are not used for image processing anyway, so 
they have no reason to switch to gnuplot >= 4.0.

We should avoid having too many gnuplot versions depending on ./configure 
options. It's better to on/off these features by some "set ..." switches.

Was there any report of a broken script?

I will do this change within one week if there is no really strong 
objection.

The problem with loadable files is there to install them. Gnuplot supports 
too many OSes. Gnuplot load path is a candidate, but ... e.g. usual MSW 
users do not have any idea about setting environmental variables.
