Jaap,

gdal_polygonize is not supported on FWTools because FWTools uses the old
gen bindings.  This doesn't cause a problem in the "usage message" part of
the script - only in the call to gdal.Polygonize() itself.

You can use OSGeo4W's "gdal-dev" package if you want to try out the polygonize
function.

Best regards,
