Steve,
I usually do the same operation with no warning message. I write a file 
with attributes in dig_att using a couple of coordinates belonging to the 
line to wich the attribute is to be assigned. As the attribute is 
assigned to the closest line (as defined by the couple of coordinates), this 
insures the correct coupling line-attribute.
The operation is faster if you edit the original file (you could have it 
in arc) deleting all the coordinates except the one you want to use to 
assigne the attribute.
Hoping this can help you.
