I'm not going to comment on the quality of the OS, but it sure as hell
is regularly causing me build headaches!

Ah, but that is available neither on Linux, nor on FreeBSD, nor MacOS. I
got it to work using this instead:

--- ARP.h       20 Dec 2005 00:48:12 -0000      1.3
+++ ARP.h       22 May 2006 15:11:16 -0000

I was hoping that'd be portable enough so we can do without an ifdef,
but haven't tried the other platforms yet.

It's just a matter of translating it down into the code with the least
amount of clutter.

Yeah, though I don't think you need to fight at the m4 level but rather
at the level of what autoconf already gives you (like AC_LINK_IFELSE).

Thanks for your efforts!

Cheers,
