If Mark agrees with you, then I'm unfortunately going to have to lobby to disable VRP by default in 4.2. I don't want to do that, but as we've seen in the signed overflow thread from a couple of months ago, reasonable users are surprised and disturbed by gcc 4.2's current behaviour. As you know, Paul Eggert has proposed having autoconf automatically pass -fwrapv when compiling with gcc. I think that would be extremely unfortunate. Disabling VRP by default will be the lesser of two evils. > Also isn't there still some regressions associated still with this change? > <http://gcc.gnu.org/ml/gcc/2007-03/msg00120.html> for the reference of > the regressions. That one is already fixed, I believe. Ian
