"make distclean" should restore the source tree to its original
condition, as if you had deleted it then run "cvs checkout ...".

It's better to run it *before* "cvs update". I use:

	make distclean &> /dev/null
	cvs update 2>&1 | fgrep -v 'cvs server: Updating '

If you get any lines beginning with a "?" at the start of the output,
those correspond to files which CVS doesn't know about. You should
determine how they got there and whether they might interfere with
anything.

If you run "cvs update" without having run "make distclean" first, the
output will be swamped with entries for OBJ.<arch> etc, making any
real issues harder to spot.
