You might like Clang with Microsoft CodeGen[1], a work in progress by Microsoft to add a Clang toolset to Visual Studio 2015 that uses the MSVC backend.
Yeah I have been following the Clang\C2 work. I guess that is what the LLVM project would rather work with Microsoft towards rather than rolling their own. It will certainly make life easier for cross-platform C++ to use Clang/C2 over C1/C2. Having to install Visual Studio to get it is a bit annoying though, I would prefer to fire up a VM with just Clang and the MSVC/Windows headers to command line compile. Visual Studio is a big install inside a VM which is annoying.
I quick question you may know the answer to, does the Windows SDK not come with the Windows C++ headers anymore? I installed the Windows 10 1511 SDK the other day but even a full install didn't give me any of the stdlib which I thought it would do? I understand they removed the compilers but I thought the headers still came with it?
Oh, bummer, I even thought the Windows SDK still had the command-line compilers. What's it good for then?
Most open-source projects don't even bother supporting MSVC, and I don't blame them one bit. MinGW-w64 gives a significantly less painful route to Windows support, and allows you to pretend MSVC doesn't exist in a lot of cases.
