The solution to this problem is indeed in the manual, but it must be 
obscurely placed because you are by no means the first user to have missed 
it:  

The ascii files created with the ARC/INFO ungenerate command must be 
placed in a directory called "arc" in your current mapset ($LOCATION/arc) 
before conversion with v.in.arc. 

(Cf. GRASS 4.0 User's Reference Manual, p. 379, 3rd paragraph 
under "Description".)
