lex and yacc: Where to get them

[Joel Hammer]

I am trying to compile a new kernel on my lindows box. The kernel went fine
but the modules are not. (What else is new?)

I get errors saying, among other things, that I need yacc and lex.
yacc and lex do no appear to exist, anywhere. However, bison exists and
appears to be a drop in replacement for yacc. Is this true?
flex exists, and appears to be a replacemnt for lex. Is this true?

Thanks,

Joel
