Hi all ,

IMO, we should be fine as long as we continue to restrict ourselves to the
use of Bourne syntax i.e. avoid wandering into the realms of the quirks
provided by bash, in both make recipes and the utility & tool scripts - I
say this only because shell shock affected  certain platforms such that
bash is not available on those platform(s) e.g. AIX.

Just my 10c FWIW ....

Now I saw, tho' too late, the folly of beginning a work before we count the
and before we we judge rightly of our strength to go thro' with it -
