Nope.
I've never seen, or heard of, anything like this. This is coming from the "./configure" step, not "make", right? I've grepped for "Video4Linux2" - nothing... Are you doing your own "autoconf" and/or "autoheader"? Possibly try doing/not doing that? You might try "make -f Mkfiles/Makefile.unx" and see what it does (won't make the rdoff stuff - do that separately, if you need it).
When I do "./configure", the resulting "Makefile" (and rdoff/Makefile) needs to have "std=c99" manually removed from cflags... after that, it works fine. (speaking of 0.98.39, of course - if you're using an earlier version... don't.)
You might post more information about just what version/distro of Linux you're running, just what the error message from "make" says, etc., but I think it's beyond me, in any case...
Good luck,
Frank
