awk should be available already from msys. Maybe somewhere on the web
someone has compiled gnuplot for MS Windows? or maybe that needs Cygwin?

this has already been done by Glynn for GRASS 7, testers needed.
Gnuplot is now optional - AFAICT GRASS's d.linegraph module is now
used as the default plotting method.
