I'm not sure what the common practice is for the JIT/interpreter side, but I would prefer to use a check in code, whether the target triple is windows, rather than using an ifdef. Most of clang is cross-compiling agnostic anyway. For the JIT that's obviously not the case, but by not using ifdefs, you get the code compile tested in all builds, not only the windows ones.
