This portability problem has been addressed in GRASS GIS 7:

http://trac.osgeo.org/grass/wiki/Grass7/NewFeatures#Imageprocessing
--> Image processing
     --> i.class: rewritten in  wxGUI, see G7:g.gui.iclass
           http://grass.osgeo.org/grass70/manuals/g.gui.iclass.html

The old i.class in GRASS 6 depends on the X Server which is not part
of Windows. With Cygwin you could get it running but it is way more
interesting to install GRASS 7 (also in parallel).
