+// commonly used POSIX functions such as open(2) and access(2), as well
+// as macro definitions for flags of these functions.
+//
+// By including this file you'll redefine open/access/etc. to
+// ::google::protobuf::io::win32::{open/access/etc.}.
+// Make sure you don't include a header that attempts to redeclare or
+// redefine these functions, that'll lead to confusing compilation
+// errors. It's best to #include this file as the last one to ensure that.
+//
+// This file is only used on Windows, it's empty on other platforms.
