correct, this will use MS libraries. If you watch Jim Radigan's Build talk (he owns C2), he talks a little bit about how the ABI is really a part of the platform and it might clarify some of this. http://channel9.msdn.com/Events/Build/2015/3-714 about 23 minutes in. Thanks, Steve (vc dev mgr)

Clang was already planning on using MS libraries/headers.

IE this is literally not different from what was already being done, without MS :)

yes, we are well aware that clang and llvm is working on targeting windows. this is clang+c2 which we will fully support.
