Same thing with the other members of the vprintf family of functions, such as
vfprintf... I remember getting particularly confused by this one in the past
and hacking together some really ugly workarounds to deal with it, when all I
really needed to do was to put the format attribute on the calling function,
instead of trying to re-declare vfprintf...
