That's really close to what I want! A fail-undefined-variables would be even closer, if the team feels it's a good addition.

Is --warn-undefined variables not sufficient?

If you want to fail recipes, would it be feasible to
set the shell to bash, and then set 'nounset' in the prolog of each recipe?

The FR is for make variable substitution, not shell variables.

Try setting:

.SHELLFLAGS := -u -c

Thu 21 Feb 2019 08:38:59 PM UTC, original submission:  

Implement an option to fail recipes on undefined variable references (similar to bash's nounset option).

I'm sure it can't be default, so would need to be enabled with an option. Would prefer an option that can be set inside the makefile, like a pseudo-target (".NOUNSET:" or something) (as opposed to a command-line flag).
