Lutz and any adventurous people,
I pulled down the 10.4.5 sources and ran make under Windoze cygwin. Got the following message when it came to the nl-sock compile.

I noticed the comment on line 61. I can't remember but I may have grabbed a icmp6.h in the far past from somewhere else -- I don't remember. Lutz, are you expecting that the icmp6.h that we have has no definition for icmp? Mine does; so I may have the "wrong" one. Here's icmp from my icmp6.h.

Yeah, it's ugly, and very different from the one in nl-sock.c. What do you think I should do? When you wrote the comment "not on Cygwin, get from other OS" in nl-sock.c, what exactly did you mean? Or, can you send us your icmp6.h that you use for cygwin builds? :)
Thanks! --Rick
***SOLVED*** (I think)
I merely obtained the GNU version of icmp6.h, and nl-socks compiled.
Here's a copy, if anyone needs it. Put it in your /usr/include/netinet directory.
(But before that, here's a board topic related to this: //http://newlispfanclub.alh.net/forum/viewtopic.php?f=9&t=3959)
