I actually asked for/suggested a common (to all distributions) rtlinux.h
(or realtime.h, or <whatever>.h) within standard C_INCLUDE_PATH or in
/usr/include/rtlinux/ that tells me what system I am running - that could
be as simple as defining one of
RTLINUX_V1
RTLINUX_V2
RTAI
KURT

Well, Stuart, we talked about that in Vienna already, and as such you
know that I consider it very important that there is a common include
directory for all dists, whatever it is called !
(I suggest /usr/inlclude/rtlinux/, and I actually added a install target
to NMT-RTL some time ago that did exactly that - installed modules into
/lib/modules/`uname -r`/misc/ and includes into /usr/include/rtlinux/.
Can we all agree on that (Paolo, Victor, ... ) ?

Well, than people will step in and ask why the hell they don't get the ns
resolution they specify :-(

Yes - we have to start it now, though.
