I've had the same discussion before, but just pulled my claim as Marc 
was involved in gcc development, and I did not feel I could make a point.

I've had the same problems, -Wall -Werror, as I consider the compiler my 
friend and if he wants to tell me something it usually pays of when I'm 
listening to him.

But, I totally understand if Marc says "it is not a libev bug", and 
rejects to add casts to proper code - to fix compiler misbehavior.

Therefore I'd be glad to get more information on the topic.
Thanks for the offer.


Markus
