Yeah, it's ugly, but it works everywhere.

Why not simply:

    $(MAKE) error 2>&1 | grep error; exit ${PIPESTATUS[0]}


Note the sentence I quoted from Philip's email.

PIPESTATUS is a bash-specific feature, so it in no way "works
everywhere".  It won't even work on all GNU/Linux systems, including one
of the most popular (Ubuntu).  And it has almost no chance at all of
working on any non-GNU/Linux system.

Oh, sorry I missed that.

It would make my "real life" job so much easier if people writing
scripts would understand that bash != sh, and that bash is not available

I admit I may have been spoilt by bash :)
