134 Currently only MinGW is supported. See the gnulib manual regarding
135 Windows sockets. MinGW has the header files winsock2.h and
136 ws2tcpip.h that declare the sys/socket.h definitions we need. Note
137 that you can influence which definitions you get by setting the
138 WINVER symbol before including these two files. For example,
139 getaddrinfo is only available if _WIN32_WINNT >= 0x0501 (that
140 symbol is set indiriectly through WINVER). You can set this by
141 adding AC_DEFINE(WINVER, 0x0501) to configure.ac. Note that your
142 code may not run on older Windows releases then. My Windows 2000
143 box was not able to run the code, for example. The situation is
0f00f2c3
LC		 144 slightly confusing because
145 <http://msdn.microsoft.com/en-us/library/ms738520>
8912421c
