What is the output of v.support?
Where did you change all L by A?
What is the type of lines in vector 
( v.out.ascii -> lines in dig_ascii is L or A)?
Have you tried v.line2area?
What is the type of attributes in dig_att (A/L)?
Are lines closed polygons 
( v.out.ascii -> are first and last coordinates for each line identical)?
Have you tried v.support map= err=tmp; d.vect err=tmp 
(available in grass5.0pre4 or CVS only)?
Which version of grass5?
