Subject: Re: [bug#59994] [PATCH] tests: Don't try to prevent flex to include unistd.h

The *command line option* --never-interactive was added
    in version 2.5.6 (along with long command line options in general).
    That version was released somewhere between 2002-04-19 and 2002-04-23;

I guess 20 years ago is long enough, barely :). Though if it's just as
easy to use the %option, why not ... since we already have to assume
flex (specifically) either way ... --thanks, karl.
