Flex 2.5.7 (Beta )

[D-O-N]

Hello ,

     I've downloaded Flex 2.5.7 Beta( April 23 , 2002 ) , however each
time I compile code generated by flex , I've got this error :

      Undefined symbol : yy_globals

      I'm trying to test the new reentrant feature of flex. I've used 
%option reentrant-bison (since my parser is bison) But I always 
got the error above. What should I do? 

      One more thing, Is there already a released version of Flex 2.5.7?
Thanx.
