Thanks! When one attempts to generate pre-processed source with clang and compile it with MSVC, you usually have to remove clang's internal intrinsic headers from the include search path, otherwise you'll end up with references to builtins that don't exist in MSVC. Adding an extra -fuse-line-directives flag is just one more thing that you have to remember for that corner-case usage.
