Comment (by teor):

 Replying to [comment:4 nickm]:
 > Hm.  With all this, -fwrapv is starting to sound pretty reasonable.

 Yes. And we can still check for overflows in the code when we need to.

 > We should also treat any unmarked sign integer overflow as a bug,
 though, IMO.

 I agree - signed integer overflows often lead to unexpected behaviour.
 (They can be detected using -ftrapv.)
