144 Currently only MinGW is supported. See the gnulib manual regarding
145 Windows sockets. MinGW has the header files winsock2.h and
146 ws2tcpip.h that declare the sys/socket.h definitions we need. Note
147 that you can influence which definitions you get by setting the
148 WINVER symbol before including these two files. For example,
149 getaddrinfo is only available if _WIN32_WINNT >= 0x0501 (that
005de2e8 150 symbol is set indirectly through WINVER). You can set this by
8912421c
LC		 151 adding AC_DEFINE(WINVER, 0x0501) to configure.ac. Note that your
152 code may not run on older Windows releases then. My Windows 2000
153 box was not able to run the code, for example. The situation is
0f00f2c3
LC		 154 slightly confusing because
155 <http://msdn.microsoft.com/en-us/library/ms738520>
8912421c
LC		 156 suggests that getaddrinfo should be available on all Windows
157 releases. */
