Second idea is to compute a double-width product,

What "standard multiple-precision arithmetic" is there in C? I am
not aware of any.
I didn't say there is. So what else might I have meant by that
phrase?
If you have widening multiplication in the language, things are
trivial. [...]
Sure. If things were different they wouldn't be the same.
