Built and tested correcty on a cygwin+vista system.
demo.pl got farther but then died with an error report:
perl demo.pl
should complain about an invalid "with":

=================================
Gnuplot 4.4.0 gets confused about binary input. PDL::Graphics::Gnuplot
should detect this and quit after a few seconds:
=================================
Gnuplot process no longer responding. This is likely a bug in
PDL::Graphics::Gnuplot
and/or gnuplot itself. Please report this as a PDL::Graphics::Gnuplot bug.

Are all the gnuplot windows supposed to stay open with their
own process? E.g.,
