I've been burned with this, too - noticed it because one of the existing
autoconf boilerplates expands into an empty list. (offhand I don't recall
if it was a vendor system or one of the bash implementations that breaks,
but since it's in a harmless place in autoconf, the error doesn't cause the
script to stop, hence it's not normally noticed unless you happen to be
tracing).
