How do you cross compile wireshark on Linux for Windows?

Someone else recently asked this question, and the answer was to file a bug. Unfortunately, no link to the bug was posted, so here I am with the same question. Here is the basic info:

./configure --build=x86-pc-linux-gnu --host=i586-mingw32msvc

[...]

 checking for connect in -lsocket... no
 configure: error: Function 'socket' not found.

config.log:

Actually I'm only doing this because I'm trying to cross compile a dissector and I'm getting pthread errors there. It looks like glib is trying to use pthreads when it shouldn't:
