I disagree with Greg.

The real Makefile has -euo pipefail - and works perfectly, even from
cron. I tend to use this in all scripts. -u in particular is useful for
picking up typos and -e makes it fail fast and early.

It's only when I attempted to redirect output that I spotted this.

The failure doesn't even break anything, it just creates noise on
stderr.

I might log a bug to fix /etc/bash.bashrc but I'm suspecting there's a
bug in make - and changing .bashrc will just hide the symptoms.

Tim.
