511 * Recent MSDN docs indicate that the MS-specific extensions exported from
512 * mswsock.dll (AcceptEx, TransmitFile. WSARecEx and GetAcceptExSockaddrs) are
513 * declared in mswsock.h. These extensions are not supported on W9x or WinCE.
514 * However, code using WinSock 1.1 API may expect the declarations and
515 * associated defines to be in this header. Thus we include mswsock.h here.
517 * When linking against the WinSock 1.1 lib, wsock32.dll, the mswsock functions
518 * are automatically routed to mswsock.dll (on platforms with support).
519 * The WinSock 2 lib, ws2_32.dll, does not contain any references to
520 * the mswsock extensions.
