It could output this information, but that would require some changes 
to the way source position is encoded for run-time errors. Currently, 
oo2c uses the module descriptor and a single integer (ie. character 
position). I think a single integer would still be enough if (for 
example) 8 bits were used for column and 24 bits for row. The current 
solution works well for me. Usually, I want the line number and a 
little bit of source code context so I have to run an external program 
anyway.
