   For prototyping a new language i usually resort to the GOLD Parser   
   Builder (very nice IDE):   
   http://www.devincook.com/goldparser/   
   You can also emit a Yacc grammar from the GOLD grammar.   
      
   For Yacc/Lex there exist some free/open-source tools, but nothing as   
   complete as an IDE.   
   Such a tool is yaccviso and there probably exist a few more.
