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. */
