I also encounter this problem on a Win XP SP2 running as a virtual
machine under virtualbox. Tried all 3.2.x installers on sourceforge.

This is what I got:

octave:1:C:\> system (sprintf ("\"%s\" --version", gnuplot_binary ()))
gnuplot 4.3.0-2009-07-08 CVS patchlevel 0 octave-mingw32
ans = 0
octave:2:C:\> [status, output] = system (sprintf ("\"%s\" --version",
gnuplot_binary ()))
error: value on right hand side of assignment is undefined

I do *not* have such problems on my laptop with win XP SP2 running on
real hardware. Very strange!
