Hi, just checked with the current experimental version (4.5.1-9), and the false positive still seems to be there if -Wold-style-cast is used. Looks like -Wold-style-cast isn't covered by -Wall though (any longer?), which made me also believe that this bug is fixed.
(P.S.: hope you won't get duplicates of this, as my lacking BTS skills needed me to resend the control message twice... if so, sorry for the inconvenience). Cheers, Stefan.
