Clang Frontend
#1

I compiled clang with gcc 4.4.4 on RHEL6.0. No error occurred. But when I use
the clang/clang++ to compile other C/C++ code, it always output two same
messages:

#2

I think this should have been fixed by r157745 of llvm. What version are you on?

#3

Thanks!
I updated the code, and try again. The messages disappeared!
