For windows to even use the gnuplot backend one requires a true console 
(i.e. pipeable) application, which is available since 
CVS-4.3.0-2008-11-21 thanks to michael goffioul. The zooming feature if 
data is piped into gnuplot requires a build with -DVOLATILE_REFRESH, 
which is available IIRC for 4.3.0. So the available windows binaries 
allow zooming.
