Perhaps because it's old and unsupported by anyone? (It doesn't even  
have a homepage.) That coupled with the ease of writing a lexer is  
probably the reason.

I've used Leex quite a lot though, and it works fine. There are a few  
minor annoyances, but no show-stoppers. (I might even get round to  
fixing them at some point...)
