  @section Windows sockets
  
  One of the portability problems for native Windows are sockets and
  networking functions.
  
  @subsection Getaddrinfo and WINVER
  
  This was written for the @code{getaddrinfo} module, but may be applicable to
  other functions too.
  
  The @code{getaddrinfo} function exists in @code{ws2tcpip.h} and @code{-lws2_32}
  on Windows XP.  The function declaration is present if @code{WINVER >= 0x0501}.
  Windows 2000 does not have @code{getaddrinfo} in its @file{WS2_32.DLL}.
  
  Thus, if you want to assume Windows XP or later, you can add
  @code{AC_DEFINE([WINVER], [0x0501])} to avoid compiling the (partial)
  @code{getaddrinfo} implementation.
  
  If you want to support Windows 2000, don't do anything.  The
  replacement function will open @file{WS2_32.DLL} during run-time to
  see if there is a @code{getaddrinfo} function available, and use it when
  available.
