+Subject: [PATCH] Use the right permissions for directory watching on Win32
+
+Using FILE_GENERIC_READ | FILE_GENERIC_WRITE access rights for directory monitoring
+might cause problems, as noted in https://gitlab.gnome.org/GNOME/gimp/-/issues/4594.
+
+ReadDirectoryChanges only needs FILE_LIST_DIRECTORY, so use that.
+
+Fixes: https://gitlab.gnome.org/GNOME/gimp/-/issues/4594
