Stupid answer: I have no idea.  ;-)

Sure.  Though I found a big deficiency: the actual number of args is not
reported to the foreigh function.  If somebody else uses 'x', then 'X'
which reports the number of actual arguments would be great, otherwise
changing 'x' should be OK.

I would if I did, right?  ;-)  So probably no.

Hmm, I think I saw plotgnuplot.c there...  Probably you mean "not
supported by a Configure script"?

the distribution):

36) ploth2 takes array of even length, making multiple plots possible.
42) Additional function added: plothrawlines: the same as plothraw,
but connects points by lines.
45) Two new functions added: rectpointtype and rectlinetype to change
style of drawing in a rectangele. Lines -2 are for frames, -1 for
axes, >=0 for the rest. Point -1 is a point, >0 is something else.
Currently supported under gnuplot only.
49) new functions rpoints, rlines, rpointtype, rlinetype,
plothrawlines,
rploth, rplothraw, rcopy added to interpreter.
52) addhelp added.
