Why that? There is a working win32 port in the contrib module/zip directly from
us, which is known to work and to be in sync with our sources.

Depending on the version, please call lwip_init() instead of calling all the
init functions yourself.

This is definitively wrong: don't pass udp_input as the input callback
function: this will lead to udp_input getting IP or ethernet packets, which it
can't decode and thus drops.
Anyway, please have a look at our examples, that's what they are there for.
