    Fix getdate.y compatability with POSIX yacc
    
    Commit 28fd0a934cdc7b3b42ce213c6d334d4edf1ab591 muted a warning from
    bison about shift/reduce conflicts in the grammer.  However, the
    extension for suppressing the warning is bison-only.  Revert that
    portion of the change and live with the warning rather than adding
    additional conditionalization.  Reported by Michael Osipov.
