See http://redsymbol.net/articles/unofficial-bash-strict-mode/ In particular read about "set -u". I know "dash" and the Solaris shell also support this, but don't know how wide spread it is. This would be a maintainer-only thing, since one cannot safely assume support is present. You would probably also find that the standard AC_ and AM_ macros have "sloppy" coding practices. -Paul -- Paul H.
