Comment 3 for bug 1741265

I am also a bit worried about this warning:

pcbnew/zone_filler.cpp: In member function ‘void ZONE_FILLER::buildUnconnectedThermalStubsPolygonList(SHAPE_POLY_SET&, const ZONE_CONTAINER*, const SHAPE_POLY_SET&, double, double) const’:
pcbnew/zone_filler.cpp:1080:42: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
                 for( unsigned ic = 0; ic < spokes.PointCount(); ic++ )
                                       ~~~^~~~~~~~~~~~~~~~~~~~~
