[vbox-dev] Build from todays SVN sync fails

[Perry Halbert]

Well that was fun and I did have a couple gerrr moments, but gcc 4.9.2 
is built, installed, and I have a new bouncing baby install of the 
latest from SVN.

Thanks you my friend for sterring me in the direction I should have 
already known but didn't. Everyday one needs to learn something and that 
is it for today. :)
