Yes, definitely. My comment was referring to the fact that the
declaration of this structure was not at the top of this .c file as
the last version of the patch is doing (would be better to declare
them at the beginning of this .c file for clarity actually). It seems
like I did not get Andres' review point, sorry for that.
