Hardly, considering that I don't have GNU BASH installed at all here ;-)
There may well be something in the script that is not perfectly
portable, but if so, please tell us exactly what, so we can fix it.
"Use GNU BASH" is not a portable answer either --- we will most
certainly not put anything in the script to deliberately prevent it
from working on non-BASH shells.
