+/* This file is supposed to be used on platforms that lack
+ sys/socket.h. It is intended to provide definitions and prototypes
+ needed by an application.
+
+ 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. */
