Hi
v2:
- Sorted the enum by alpha (was sorted by algorithm age)
- Use normal rotate here, xor not needed
- Comment cleanup
- Remove *empty* comments
- Unify one be/le path
- Remove #define round
- Move to if(BB_ENDIAN) instead of #if
- Lauri
PS: There were existing #if blocks in the same file, just above in the
md5 code. The requirement felt kinda weird with those there...
