AC_DEFINE something like:
@example
-AC_DEFINE(check_version, stringprep_check_version, [Rename check_version.])
+AC_DEFINE(check_version, stringprep_check_version,
+ [Rename check_version.])
@end example
The @code{stringprep_check_version} function will thus be implemented

+@section Windows sockets
+
+There are several issues when building applications that should work
+under Windows. The most problematic part is for applications that use
+sockets.
+
+Hopefully, we can add helpful notes to this section that will help you
+port your application to Windows using gnulib.
+
+@subsection Getaddrinfo and WINVER
+
+This was written for the getaddrinfo module, but may be applicable to
+other functions too.
+
+The getaddrinfo function exists in ws2tcpip.h and -lws2_32 on Windows
+XP. The function declaration is present if @code{WINVER >= 0x0501}.
+Windows 2000 does not have getaddrinfo in its @file{WS2_32.dll}.
+
+Thus, if you want to assume Windows XP or later, you can add
+AC_DEFINE(WINVER, 0x0501) to avoid compiling to (partial) getaddrinfo
+implementation.
+
+If you want to support Windows 2000, don't do anything, but be aware
+that gnulib will use its own (partial) getaddrinfo implementation even
+on Windows XP. Currently the code does not attempt to determine if
+the getaddrinfo function is available during runtime.
+
+Todo: Make getaddrinfo.c open the WS2_32.DLL and check for the
+getaddrinfo symbol and use it if present, otherwise fall back to our
+own implementation.
