I don't understand this sentence. Are you saying it prefers forward slashes or backward slashes (or uniform slashes)?

This is interesting. I'm surprised that errors are coming from llvm tools, as the llvm path libraries treat forward and backward slashes (on windows) as equivalent at a very low level. Could you try to reduce this to a issue to figure out which specific slash in the command is causing the error? I want to make sure we're not working around a bug here...
