Note that, for the record, LLVM is perfectly correct to spew these
warnings.  These are due to funny games that libstdc++ is playing to make
sure that 'std::cout' and friends are initialized before they are used.

Despite it being correct, it's not useful at all.  Because of that, I
applied this patch:
http://mail.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20040816/017351.html

... which should silence these warnings.

For your other problems, I would recommend (like others) that you rebuild
your CFE.  Please let us know if you have any other problems!
