This is why for embedded C[1], they are adding types which the user is able to decide which behavior they want instead of just being undefined. Let me make the point that signed overflow has been undefined since before the C standard was finialized and in fact there is a nice paper/book called "C Traps and Pitfalls[2]" which mentions all of this back in 1988.
