The aesthetic changes are: - 'warning', 'error', and 'fatal' are all colored magenta, red, and red respectively. - The warning annotation [-Wsomething] shares the same color. - Warnings and errors are also bolded (this is consistent with what other compilers do). A new flag has been added to control the behavior: -fdiagnostics-color=(always|auto|never) This flag is 'auto' by default. However, auto-detection is not implemented yet, so it effectively it defaults to off.
