TBH, I have not tested on Windows. However, by construction, I've hopefully made sure the Windows and non-Windows are isolated and separate - either with checks whether target is or isn't Windows or with check about a particular kind of stack probing (e.g. attribute "probe-stack"="inline" means not Windows).
