Perhaps bug #59708 is a better candidate for this issue here than bug #48580,
particularly in the light of bug #48580 comment #18 and #19. Can someone change
the resolution of this here to duplicate that instead?

The proposed interface, with its references to global flags set by operations
that otherwise have values but no side effects, is not a good match to the
nature of C as a high-level language; the source code arithmetic operations
should not be presumed to have any particular correspondence to machine
instructions that might set flags.  Instead, I proposed a more appropriate
interface for operations with explicit overflow behavior in bug 48580.
