// This header is needed because winsock2.h and windows.h are banned from including from headers and SocketAddress.h needs some struct definitions from those headers.
// These definitions were copied from Windows SDK headers. Comments, #ifdefs and special annotations like _Field_size_bytes_ were removed. This is fair use, see Oracle v. Google.
