yes, they are annoying aren't they.  They all come from google's
unittest
library.  I think it is best to fix them upstream at google.

This has already come up on the mailing list.  I'm not sure what the
resolution
was.

I reported this error before a number of weeks ago. I am not an llvm 
developer and I realize there are other priorities but someone should 
fix this eventually so the rest of the 'make' can run to conclusion.
