So how should this be fixed? Shall I just check if the system is
FreeBSD (for example by checking that __FreeBSD__ is defined at all),
and if yes, then include <osreldate.h>, possibly with #undef to
Personally, I'd just write Autotools -style cheks that produce output
of the like #define HAVE_SYS_???_IOCTL_METEOR_H and we could forget the
whole FreeBSD dependency stuff and focus on finding the headers, that's
were the problem was anyway.
Tell your preferred approach and I'll make a patch and submit wherever
you like, this mailing list perhaps?

Okay, user error. Disregard that.

Also my error. I have a SCons compiler script that does not duplicate
linker flags (since --as-needed is not usually specified). Sorry for
Yet another thing about compiling. I have linux-ppc (current Debian
testing, GCC 4.1.2) box where I also compiled the program, and ran into
problems trying to enable XviD (latest SVN, refreshed today). The check
fails with ERROR: XviD not found. I read the logs and it appeared the
problem was that it did not find math library with the compiler string
it was using.
I edited configure line 1310:
enabled xvid && require XviD xvid.h xvid_global -lxvidcore
Changing the line to:
enabled xvid && require XviD xvid.h xvid_global -lxvidcore -lm
Solved the problem.
