I'm afraid you are fixing the symptoms, not the cause.
For example, AC_CANONICAL_SYSTEM is converted by autoupdate to

AC_CANONICAL_TARGET([])

I understand that the role of autoupdate is to create a script conforming
with the today's guidelines. I don't think that giving an empty argument
to AC_CANONICAL_TARGET is what we recommend users to do.

The problem appears to be in the definition of AU_DEFUN. It adds
parentheses unconditionally. Maybe we need another AU_DEFUN, without
parentheses?
