Re: Help with gram.y (UNDER)

It seems like bison is confused by having that '(' just after an
optional syntax (UNION). If I place something after OptUnder (USING just
to pick a token), then everything works fine (except of course the
spurious USING becomes part of the syntax).

Does the '(' have some kind of second-class status as a token that would
cause this wierdness?
