One of the latest mods in the sql upgrades file has a line that's mysql4
Make of that what you will.
But the reason for this message, is to point that out for those who haven't
moved to mysql4. You need to look into doing so, imho. I can't imagine that
the OSDN guys will continue to support mysql3 for any extended period of time
because they're using v4. Again, my opinion, not anything I've heard/read
