Finish (?) importing the Linux ext2fs files that our GPL'ed ext2fs
    files seem to be based on.  Don't bother importing <asm-i386/string.h>
    just to get the Linux implementation of memscan() which is appended
    to our i386-bitops.h.  The BSD skpc() should have been used instead
    of memscan().
