44 Currently only MinGW is supported. See the gnulib manual regarding
45 Windows sockets. MinGW has the header files winsock2.h and
46 ws2tcpip.h that declare the sys/socket.h definitions we need. Note
47 that you can influence which definitions you get by setting the
48 WINVER symbol before including these two files. For example,
49 getaddrinfo is only available if _WIN32_WINNT >= 0x0501 (that
50 symbol is set indiriectly through WINVER). You can set this by
51 adding AC_DEFINE(WINVER, 0x0501) to configure.ac. Note that your
52 code may not run on older Windows releases then. My Windows 2000
53 box was not able to run the code, for example. The situation is
54 slightly confusing because:
55 http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winsock/winsock/getaddrinfo_2.asp
56 suggests that getaddrinfo should be available on all Windows
57 releases. */
