What they want is that you use

    %name-prefix "base_yy"

instead of

    %name-prefix="base_yy"

That makes the warning go away.

The %something=something syntax is not documented anywhere, so it looks
like it worked more or less by accident.  We don't use it anywhere else
either (e.g. %expect 0, not %expect=0).
