> Include IBM 1.0/1.1 Bugs for compatibility

I am, to put it mildly, not the greatest fan of Microsoft, or of most of their products. But that just sounds like a flag to avoid breaking backwards compatibility by fixing bugs that people have come to rely on.

And a strong focus on backwards compatibility most certainly is a principle by which Microsoft operated for years.
