that problem should be solved using a cygwin snapshot dll
instead of 1.7.9-1 one.

I should look in all the bug reports reporting cygwin as "OS", thank
for the link.

you can try to use the fltk plotting interface instead of gnuplot
default one:

   graphics_toolkit("fltk")
   x=1:10;
   plot(x,x)

Be aware that the octave "print" command does not work with fltk,
but you should be able to make a windows "print screen copy".
