------- Comment #3 from fang at csl dot cornell dot edu 2005-11-04 17:56 ------- Am I correct in expecting that const_cast<...> should pass -Wcast-qual without warning? That's the way I use it (in the few and rare cases that demand it) and it's met my expectations thus far. I'm kind of surprised I haven't tripped this bug myself, but that's because I stopped using C-style casts long ago, enforced by -Wold-style-cast -Werror. Adding -Wold-style-cast does trip a warning about old casts with the posted code, but nothing further about discarding qualifiers (gcc4).
