Which compiler were you using?

It's still defined in 10.0-CURRENT at least in <sys/param.h>:

http://svnweb.freebsd.org/base/head/sys/sys/param.h?view=annotate#l77

You are right, I see in the comments describing __FreeBSD_kernel__, that
__FreeBSD__ should be tested for as well, for the benefit of "older
FreeBSD versions, 3rd party compilers".

So Dirk, I think we now have this horror:

#elif defined(linux) || defined(__linux) || defined(__FreeBSD__) ||
defined(__FreeBSD_kernel__) || defined(__NetBSD__) ||
defined(__OpenBSD__) || defined(__DragonFly__)

I'm not sure what (__linux) refers to and may not be needed.

Some others might be:

defined(__APPLE__) for Mach, or Mac OS X
defined(__GNU__) for GNU/Hurd

Yet more examples:
