These warnings
Warning 1: Field Riv of width 1000 truncated to 255.
Warning 1: Field Site of width 1000 truncated to 255.
Warning 1: Field type of width 1000 truncated to 255.

and this error

come from the OGR library. If you want these messages to be improved,
please ask on the GDAL dev ml. GRASS can not change these messages.
