CVS / cvsup problems

After having problems with a kernel compiled from sources from yesterday I
decided to go back to a known good kernel from 2004.11.07.07.00.00.
Unfortunately I cannot seem to compile it:

===> autofs (depend)
make: don't know how to make autofs_vfsops.c. Stop
*** Error code 2


I recall a commit-message from last week with the wrong date. Could it be
that a recent commit having to do with vfsops got the wrong timestamp, thus
messing up the source repository?
