off the top of my head, i know two languages that start counting at 1:  
pascal and lua. since i've forced myself to forget all the cobol i  
ever knew, i simply accept that cobol is among those.
changing it: you can override the error reporting methods in your  
generated parser and simply add 1 to the column (charPositionInLine).  
does that sound helpful?

cheers,
