Build problem in TOT llvm

I'm getting a lot of these from TOT make:

/Volumes/MacOS9/gcc/llvm/include/llvm/Analysis/LoopInfo.h: In instantiation of 'llvm::LoopInfoBase<llvm::BasicBlock>':
/Volumes/MacOS9/gcc/llvm/include/llvm/Analysis/LoopInfo.h:886: instantiated from here
/Volumes/MacOS9/gcc/llvm/include/llvm/Analysis/LoopInfo.h:573: warning: 'class llvm::LoopInfoBase<llvm::BasicBlock>' has virtual functions but non-virtual destructor

Weird, I did not get this error. If following helps, please apply.
Thanks,

It does help, I have checked it in. Thanks.

Thanks!
