This is not likely to happen -- Windows XP is the minimum OS we are
supporting. However, it might make sense for us to explore creating
the pre-built binaries with XP support enabled. If it proves to be
impossible (IIRC, using XP support could change the compiler features
we can use from MSVC), we should at least cause the installer to fail
on XP and lower (we should fail on Win2k and lower no matter what, but
since I don't create the installers, it's easy for me to say this).

clang can self-host on Windows, but the linker support isn't there for
producing executables. MSVC ABI compatibility is coming along nicely,
but not to the point where we can use LINK.exe to link clang (that I'm
aware of), and lld support for PE32 files is also coming along nicely,
but not completed yet either.
