I wouldn't call anything regarding Windows "supported" at this stage. At
best any support is experimental and in-progress. Right now we're trying to
get to the point
where the Windows build doesn't regress.

No Microsoft compiler is supported; It's Clang only right now.

Is any Microsoft platform as a target supported from any compiler?


I'm not 100% sure I understand the question, but I'll try and answer.

I've only built libc++ natively on Windows 10 using Clang 4.0 with either
MSVC 2015 or 2017 as the native toolchain.
