If memory serves K&Rv1 didn't talk about overflow, yes.
My K&R V1 says in Appendix A (C Reference Manual) Section 7: . . .The handling of overflow and divide check in expression evaluation is machine-dependent. All existing implementations of C ignore integer overflows; treatment of division by 0, and all floating-point exceptions, varies between machines, and is usually adjustable by a library function.
In chapter 2, section 2.5 it basically says the same thing.Those are the only two places the index indicates that 'overflow' is described.
