--- Comment #2 from Thomas Koenig <tkoenig at gcc dot gnu.org> --- Having had occasion to look at a few hundred multi-line error messages today, I have now changed my mind on what I would consider best :-) I now think different colors for primary and secondary error message (if we stick with a maximum of two) is actually quite good. What would help a lot if the markers (1) and (2) in Error: Duplicate statement label 10 at (1) and (2) were also colored the same as the two markers under the text of the program. Would this be doable / would others also find that useful?
