FWIW, in my humble opinion, verbosity of configure code should not
prevent "more correct" functioning here.  IOW, I like Bruno's version
better here; if only because the current version of the code already
provoked confusion with users, at least Bruno.

(As a less relevant aside, Bruno's version is probably faster, too.)

Just my 2 cents.
