Summary: can't support ipv6 when compile with mingw

Initial Comment:
hi,
apologize if i post duplicate. I'm new to sf.net


I'm using mingw32(gcc 4.3.3) and windows7sp1 to compile privoxy. have two problem:
1. got an error

jbsockets.c: In function ‘get_host_information’:
jbsockets.c:979:22: error: ‘NI_MAXSERV’ undeclared (first use in this function)
jbsockets.c:979:22: note: each undeclared identifier is reported only once for e
ach function it appears in
make: *** [jbsockets.o] Error 1

2. after edit the source: 
 #define NI_MAXSERV    32
i compile successfully. But it didin't support IPV6.

I wonder whether it a bug of configure or I miss some package

Message:
I'm really sorry. I installed a latest MSYS. The problem disappeared. It
seems the older gcc cause the problem.

Message:
Strange. In the past setting WINVER seems to have been sufficient. Can you
try adding _WIN32_WINNT?

Is this the workaround you were thinking of?

Message:
I think it's because getaddrinfo need _WIN32_WINNT >= 0x0501
and there is no _WIN32_WINNT defined when configure 
you can work around this.

Message:
The missing NI_MAXSERV definition is a bug that is already worked around in
CVS. Unfortunately it wasn't discovered until after the 3.0.19 release.

This should only be a problem when Privoxy is compiled on Windows without
IPv6 support, though.

Are you configuring with --enable-mingw32?
Can you attach the configure output?
