"But I don't want to go among mad people," Alice remarked.
"Oh, you can't help that," said the Cat: "we're all mad here. I'm mad. You're mad."
"How do you know I'm mad?" said Alice.
"You must be," said the Cat, "or you wouldn't have come here."

Would 4♠ be natural or a cue bid over 4♦? If North thinks 3♣ showed a major and it isn't ♥...

4♠ would be natural, because 3♠ over 3♥ is forcing raise with fit ♥.
So bidding 4♦ doesn't yet exclude the opportunity that partner has 4♠
That's why 5♣ is picked to show fit in diamonds and control.
So it's not skipped control, just continuation of the stayman started auction.

So, if 4♠ would be natural, then 5♣ shouldn't deny ♠A. What about ♥A?

The controls that are shown and denied by cue bids is programmed into the GIB code, not in bidding rules. I was reading it a few days ago, and having a hard time understanding it. It seems to get things wrong quite a bit (that's why I was looking at it), I think because it doesn't know which bids would be natural or artificial according to the bidding rules. So once it sees a cue bid, it assumes you've denied the control in all the suits skipped along the way.
If I can figure out how it works, I'll try to correct it.

i dont mind that GIB didnt bid 4♠. I think that the explanation for 5♣ should not have "7-8421 HCP in ♠" if GIB considers 4♠ natural.

That's what barmar explained above, yes. If I understood correctly, when making the bid GIB understands that, but when pulling the explanation out, it doesn't.
