The exact same thing happened to me last night when I CVSup'd Monday's
changes and tried recompiling my kernel. I think I traced it to the
following commit, since a kernel with the previous days source worked
fine:

Log:
Removed statically configured mount type numbers (MOUNT_*) and all
references to them.
The change a couple of days ago to ignore these numbers in statically
configured vfsconf structs was slightly premature because the cd9660,
cfs, devfs, ext2fs, nfs vfs's still used MOUNT_* instead of the number
in their vfsconf struct.
