You mean git clone here, right?

I tried these both version. It says I am up-to-date.
Then I just cloned the git tree externally to make sure I am not fooled 
by some obsolete remote path, broken updates or wrong caching etc. When 
doing so I assume I get the latest and greatest. But the tree is 
essentially the same as in tools/ioemu-remote.
What were the latest changes you submitted? What changeset should fix this?

Sure. This was just a check to be sure.

Andre.

BTW: What were the reasons to use git here? Isn't that making the whole 
building process more complicated (let alone forgotten updates due to a 
separate repository)?
