147 | Currently only MinGW is supported. See the gnulib manual regarding | |
148 | Windows sockets. MinGW has the header files winsock2.h and | |
149 | ws2tcpip.h that declare the sys/socket.h definitions we need. Note | |
150 | that you can influence which definitions you get by setting the | |
151 | WINVER symbol before including these two files. For example, | |
152 | getaddrinfo is only available if _WIN32_WINNT >= 0x0501 (that | |
153 | symbol is set indirectly through WINVER). You can set this by | |
154 | adding AC_DEFINE(WINVER, 0x0501) to configure.ac. Note that your | |
155 | code may not run on older Windows releases then. My Windows 2000 | |
156 | box was not able to run the code, for example. The situation is | |
157 | slightly confusing because | |
158 | <http://msdn.microsoft.com/en-us/library/ms738520> | |
159 | suggests that getaddrinfo should be available on all Windows | |
