Hi,
the INSTALL file say:
* Flex and Bison are needed to build a CVS checkout or if you changed the
actual scanner and parser definition files. If you need them, be
sure to
get Flex 2.5.4 or later and Bison 1.50 or later. Other yacc
programs can
sometimes be used, but doing so requires extra effort and is not
recommended. Other lex programs will definitely not work.
I think shall be:

actual scanner and parser definition files. If you need them,
be sure to
get Flex 2.5.4 or later and Bison 1.875 or later. Other yacc

sometimes be used, but doing so requires extra effort and is not
recommended. Other lex programs will definitely not work.
