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