The first picture of Gackt (the one on the left) is from an album which was released in March 1998, the first pictures of Squall showed up in late 1998. So whatever was "made clear in another thread" is not entirely true.

Don't get me wrong, I don't want Squall to be modelled after a real person (so I would be glad if anyone could disprove what I wrote above), but this "rumor" might be true. And as the picture of Gackt is older than Squall and really looks like him you can't eliminate any possibility of it.
