No, the error has nothing to do with reprojection. I just doesn't load the tile for some reasons. Are you sure you are getting these errors only for projected requests? Can you provide some URLs that work and don't work?

We don't use Windows and we don't have customers who are using Windows/OSGeo4W, so there is little incentive to build OSGeo4W packages (for now). Volunteers are always welcomed, though.
