Oh sorry, then I misunderstood that completely. I thought the warning would 
warn if there were no parentheses.
I am absolutely fine with the other warnings. Although I sometimes 
encounter an annoying one about library functions declared with 
'warn-unused-result' (or something like that). If I am not interested in 
the result, I don't think the code would improve very much by fooling it 
into thinking I am. And not being interested in the result is often a sign 
of laziness or it not being clear beforehand how to solve possible error 
conditions. In that case patching it up by casting to (void) or some other 
trick only serves to hide permananetly what could be a genuine problem, so 
that you now know for sure it will be never fixed.

So I am all for deleting unused variables, whose presence is an errror or 
legacy of now rewritten code. Deleting unused functions IMO is already of 
more doubtful use, if the finctions are part of a generally useful 
infra-structure. But silencing errors that have a vague ring of truth to 
them by a meaningless trick is probably something that is better to refrain 
from.
