[vbox-dev] Build from todays SVN sync fails

[Perry Halbert]

I see.  I usually don't read a lot of the Linux kernel blogs due to so 
much infighting but this one was clean and concise.

I also realize the headache of trying to keep this program going with 
all the changes happening all over the place and really, really, 
appreciate your work and help.
