Changes in Code:

1. SHAvite-3.c
   - Fixed typo in the in the implementation (number of bits vs. number of 
     bytes issue):

          local_bitcount+=BlockSizeB;
      became
          local_bitcount+=8*BlockSizeB;

2. SHAvite3-256.h
   - Incorporated the tweak of SHAvite-3:
          rk[17] ^= counter[1];
      became
          rk[17] ^= ~counter[1];

          rk[58] ^= counter[0];
      became
          rk[58] ^= ~counter[0];

          rk[87] ^= counter[0];
      became
          rk[87] ^= ~counter[0];

          rk[127] ^= counter[1];
      became
          rk[127] ^= ~counter[1];

3. SHAvite-512.h
   - Incorporated the tweak of SHAvite-3:

          rk[35] ^= counter[3];
      became
          rk[35] ^= ~counter[3];

          rk[167] ^= counter[0];
      became
          rk[167] ^= ~counter[0];

          rk[443] ^= counter[2];
      became
          rk[443] ^= ~counter[2];

          rk[319] ^= counter[1];
      became
          rk[319] ^= ~counter[1];
