This is already in MariaDB.

This one too.
Agree that we should look at adding the first two ones to MariaDB too,
if they make sense. I did read up on bug 44927 - auto increment
counter, and still not sure if Serg or Zardosht is right.
When checking the code, it looks like using HA_AUTO_PART_KEY in the
engine is the right way to go. After all, this is just a check if we
should allow auto_increment as a secondary part of a key.
In this case there is no patch to add to MariaDB.
Serg, can you please verify this.
Regarding http://bugs.mysql.com/bug.php?id=45458, it would be good
to use the new CREATE options we have in 5.2 to store the fact if a
key is clustered or not.
Serg, would you like to review the patch and see if it can go into 5.2
or 5.3 ?
