It seems to me that we heard awhile ago that Access no longer generates
these non-spec-compliant queries --- ie, it does say IS NULL now rather
than the other thing.  If so, it seems to me that we ought to remove the
parser's = NULL hack, so that we have spec-compliant NULL behavior.

Anyone recall anything about that?  A quick search of my archives didn't
turn up the discussion that I thought I remembered.
