No you usually can't do that. these function are often virtual, so if
you change the prototype you need to change it in the whole
inheritance. furthermore even if not virtual you would still need to
cahnge all the caller.
The reasons for all the 'unused' parameter is that binfilter is
essentially a gutted version of the old product that is there only to
convert old format...
In some case the parameter are 'unused' even in 'normal' code, because
a virtual function was designed with the idea thaty you 'might' need a
give info, but practically in that sub-class you really don't care
about it... just because you don;t care for that sub-class doesn't
mean that any sub-class won't... and leaving the name in, allow the
reader to actually understand what information is available - yet
unnecessary for now.

So no, you can't practically remove the parameter... and leaving the
parameter name, ableit inside /* */, is nicer because then you know
what that parameter is ... imagine foo(int,int,int,int) compared to
foo(int /* x_pos*/, int /* y_pos */, int /* legnth */, int /* width
which one would you prefer reading ? (from the point of view: I don't
know anything about foo() )
