[LLVMdev] Unable to build PBQP/Graph.h with libc++

Hi, everyone. Today I was trying to build LLVM with libc++ and C++11 enabled, and I ran into this:


Basically, PBQP/Graph.h forward-declares classes, then tries to get iterators for std::lists of those classes. This is technically undefined behavior. I tried fudging with the order of declarations for a while, but gave up after realizing there's not an easy way out.

Is anyone else building LLVMCodeGen with libc++ and C++11? Is anyone else seeing this?
