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