Add a $gnu parameter to make use of the aforementioned -g flag, and a $order parameter to make use of the -n flag in concatfragments.sh
The concat warn parameter can now be any string (and needs to include the appropriate commenting character) and will then override the default (which still gets printed when warn=>true). Signed-off-by: martin f. krafft <madduck@madduck.net>
