There.  Check $<ttype>-1.  ($1 is the value of identifiers, $0 is the
(non-)value of the action in parmlist_or_identifiers just before
parmlist_or_identifiers_1, $-1 is the value of maybe_attribute before
that, but you need the <ttype> to specify the type whenever you're taking
a value off the parser stack like this, or when using the value of a
mid-rule action.)
