He replied only to my email and didn't include cfe-dev.

I'm starting to repeat myself, there's no "clang developers" in the sense
you understand. There's people employed by companies and paid to work on
stuff those companies find important. Chromium team cares about Windows
support the most and as far as I know they're the main contributors for
VC++ ABI stuff. The open source community (clang developers) would love to
have Clang working seamlessly on Windows but haven't had the time to
address it. There needs to be someone to drive this effort and we don't
really have that someone right now. So whoever finds these issues important
can either step up or wait for someone else to get this done, when and if
they get to it.

We went through this documentation issue in the other thread. As for libc++
on Windows, it's not much different from anything else, it's not officially
supported because nobody cared enough to get it working. There's been a few
efforts, you can search the mailing list, I don't know the exact details, I
think someone recently asked about it.
