I don't really see the point in bringing in the (void) casts. We  
explicitly removed them back in 2004/2005 for large parts of base when it  
was agreed that they are just eyesores mostly, and - since we do not put  
them in new code we write, either - the best we can achieve is an  
inconsistent mix.

Stylistic changes such as those only make sense (IMO) when we can hope for  
consistency and/or check for it or enforce it somehow.
