[LLVMdev] Using C++'11 language features in LLVM itself

Oh I certainly don't expect anyone to keep supporting the ancient VS
2005 compiler. I'm just providing feedback on our usage, as asked. I
personally would think that VS2010 was reasonable to support for future
development though. Due to the C++ ABI changes (particularly their
runtime and memory management), as long as people want to binary
integrate with existing software, they can't upgrade their compiler as
they'd like.
