I have a little c++ hobby project I am working on in which I used the "thread" class that is part of c++11.  Apparently, GCC (G++) doesnt support these new features before version 4.8.1.  On google compute engine the disk image I like to use is the debian-7-weezy, and it uses a 4.7 version of GCC.  I spent and hour or two today trying to compile 4.8.1 from scratch, but to no avail. 

If you can walk me through how to get 4.8.1 compiled and installed on there I will send you 0.02BTC.  If you look at my previous posting history, it is almost exclusively me asking computer questions and then paying people for helping me.  I have paid 3 similar bountys in the past.  I will pay you if you successfully help me.
