Attached, a couple of trivial patches - The first builds on recent changes in
the RTAI build system to work round the symbol warnings. I don't think the
original hack of moving Module.symver out of the way really worked anyway.
The second patch cleans up a couple of new temp files that recent versions of
kbuild generate - Would it not be easier to generate a list of file names for
DISTCLEANFILES at configure time rather than having to make additions across
multiple GNUmakefiles ?
Regards, Paul.
