This is badly conceived, unfortunately. This conditional disables ping6
at least for OpenBSD, GNU/kFreeBSD, and OpenSolaris.
* Solaris has IPV6_RECVHOPLIMIT, but lacks IPV6_2292HOPLIMIT.
* OpenBSD, FreeBSD, and kFreeBSD all have IPV6_RECVHOPLIMIT,
as well as IPV6_2292HOPLIMIT, but the latter is reserved
for kernel code, unless manually specified.
Ah, that wasn't my intention. I did sit for a while thinking of the
logic here, and tried it on GNU where we have IPV6_HOPLIMIT and such.
I'll think a bit more, if you have a solution please tell.
Thus BSD and Solaris will presently fail in building ping6
by default, in spite of our source being fully functional
also for them.
Yeah, my fault.
