Comment #1 on issue 452 by erik.corry: Many parameters declared but unused.
http://code.google.com/p/v8/issues/detail?id=452

-Wall normally implies -Wunused, but not -Wunused-parameter.  Did you use  
-Wextra or
is there some version of gcc that automatically turns on -Wunused-parameter  
when you
use -Wall.

I don't feel that -Wununsed-parameter is useful.  There are lots of good  
reasons not
to use parameters (virtual functions for example) and I don't think that  
cluttering
the code with unused-markers makes things more readable.

If gcc is switching on -Wunused-parameter as part of -Wall I would prefer a  
patch
that reverses that.
