How to make "configure: WARNING: unrecognized options: - -enable-…" an error

When an AC_ARG_ENABLE() for a given arg is missing, one only seems to
get a WARNING from configure such as:

configure: WARNING: unrecognized options: --enable-foo

Is there any way to make this an error so that configure [ideally,
exits immediately] and returns !0?

It's too easy to miss such a warning for a critical arg and continue
down a path of ultimate failure.
