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