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).
