Personally, I think signed wrapping is only useful very occasionally - 
and unsigned wrapping only slightly more often.  But when you need 
wrapping, it is a lot more efficient to have it than to have to mess 
around with checks for overflows.

I don't like compiler flags as a solution here, because it is 
disconnected from the code.  (Though flags are excellent for when you 
have to work with code written by someone who doesn't understand the 
language and has only tested with inferior compilers.)  If I have code 
that makes use of additional semantics, like wrapping integers or 
invalid pointer casts, I put the flags in the code as pragmas (or gcc 
function attributes).  That way the code will work regardless of the 
flags used to compile the code.  It also gives a fine place to put 
comments explaining the issue.

I think it can be agreed that sometimes the wrapping is useful, and 
sometimes it is a programming error.  But people disagree about the 
split, both for signed and unsigned types.

There are many good reasons for choosing C++ other than efficiency.  It 
is a well-established fact that in almost all code, only small sections 
are performance critical.  That does not mean we want intentionally 
inefficient code in the rest of it, of course.  And if the code gets 
full of run-time checks then it /would/ end up as inefficient.
