   Yes there are, but they are lex/yacc-like implementations, not lex/yacc   
   itself. All are LALR(1) featured solutions.   
      
   Look at the following:   
      
       * Parsifal Anagram (http://www.parsifalsoft.com/)   
       * Bumble-Bee Parser Generator (http://www.bumblebeesoftware.com/)   
       * UltraGram (http://www.ultragram.com/)   
       * JS/CC (http://jscc.jmksf.com)   
       * GOLD Parsing System (http://www.devincook.com/goldparser/)   
      
   Best regards,
