My experience with lex and yacc has been mostly good.  The one thing
that bothers me is that the generated parsers are not reentrant,
making it slightly tricky to use them in a library.

I don't personally mind the tool dependencies, but I'm sure there
would be many complaints from people running obscure operating systems
where these tools are not available (or worse, buggy).

As long as I'm not the one writing the parsers, I don't really care.
