From fa80fc2b311b689c41b4ee2913f6bfb9f7c159c6 Mon Sep 17 00:00:00 2001

Subject: add a -g flag to concatfragments.sh to disable GNU extensions to
 find, sort and xargs; makes concat work on Solaris.

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
