The front-end would have to track column numbering for to allow use to
use carets in errors.

As for errors, only errors that go through the gcc error system shows
in colours.  So would have to modify the frontend accordingly in that
case...

eg:

void main() { int a = void; }

gdc -fdiagnostics-color -Wunused foo.d

gdc -fdiagnostics-color -Wunused -Werror foo.d
