You will have to remove the -DHAVE_SIN6_LEN in the Makefile. Also use the 
included net_udp6.c file that I've changed to make sute that this #defined 
is everywhere it's needed.

I've just tested under Linux and the IPV6_V6ONLY or IPV6_BINDV6ONLY is 
missing, so I will need to make some changes to have this working in 
dual-stack mode (bind on IPv4 and IPv6 simultaneously).  It will work fine 
in IPv4 only or IPv6 only mode (+set ip <ipv4|ipv6 address>).

I'm considering using the IPv6 USAGI stack for Linux as its IPv6 support is 
more up-to-date.

Hope this helps.
Florent.
