Hi Yasumasa,

FYI, I have been working for a time on a major rewrite of the way we 
handle Windows compilation, which will support cygwin, msys2, wsl1, wsl2 
and wine-on-linux, and doing all of this in a cleaner and much more 
unified way than we currently do. However, this is far from ready, and 
most likely I'll have to continue working with it after my upcoming 
vacation. So in the meantime, if your fix solves the immediate problems, 
I think we should take it in. The patch itself looks good to me.
