Sorry about that.  It was a missing apostrophe.
I installed the corrected version below.

That's already done.  Here's the comment:

# Furthermore, it is okay for a non-cache variable initialized to empty in one
# run to be unset in another run.  This happens when, for example, cache update
# code tries a number of values in LIBS and eventually restores LIBS to its
# original value. If LIBS was previously unset, it will have become set and
# empty.  (OTOH, cache variables indicate the result of the test even if they
# are empty, so we have to be strict about them.)

Nicolas's problem is that his shell's "set" command outputs "X=''"
whereas other shells say "X=".

Nicolas, can you please check that this revised patch does the trick?
Thanks.

        This is a corrected version of yesterday's patch.
