521 * Recent MSDN docs indicate that the MS-specific extensions exported from
522 * mswsock.dll (AcceptEx, TransmitFile. WSARecEx and GetAcceptExSockaddrs) are
523 * declared in mswsock.h. These extensions are not supported on W9x or WinCE.
524 * However, code using WinSock 1.1 API may expect the declarations and
525 * associated defines to be in this header. Thus we include mswsock.h here.
526 *
527 * When linking against the WinSock 1.1 lib, wsock32.dll, the mswsock functions
528 * are automatically routed to mswsock.dll (on platforms with support).
529 * The WinSock 2 lib, ws2_32.dll, does not contain any references to
530 * the mswsock extensions.
