45 * access the selectively exposed content. Inclusion of "winsock.h",
46 * subject to the __USE_MINGW_WINSOCK_DEFAULT feature test, declares
47 * the necessary WinSock API, choosing between the WinSock v1.1 API,
48 * and the WinSock v2 API, on the same basis as the similar choice

111 * by the GetAddressByName() function, (also declared in this file), which
112 * is declared as deprecated in WinSock v2, (and thus, we would not expect
113 * any such dependency on this WinSock v2 specific <winsock2.h> data type).
114 * This Microsoft API design is critically flawed, but we can mitigate the
115 * fault by defining the SOCKET_ADDRESS structure here, whence we make it
