       bcopy, bcmp, bzero, ffs - bit and byte string operations

       void bcopy(b1, b2, length)
       char *b1, *b2;
       int length;

       bcmp(b1, b2, length)
       char *b1, *b2;
       int length;

       void bzero(b1, length)
       char *b1;
       int length;

       int i;

       The functions and operate on variable length strings of bytes.  They do
       not check for null bytes as the routines in do.

       The function copies length bytes from string b1 to the string b2.

       The function compares byte string b1 against byte string b2,  returning
       zero  if	 they  are  identical,	non-zero  otherwise.  Both strings are
       assumed to be length bytes long.

       The function places length 0 bytes in the string b1.

       The ffs finds the first bit set in the argument passed it  and  returns
       the  index  of  that  bit.   Bits are numbered starting at 1.  A return
       value of 0 indicates the value passed is zero.

       The and routines take parameters backwards from and
