Subject: Updating strange attack boards

I decided to stop chess programming but even the latest version of my program
sucks. How can I quit in peace?
It calculates this attack information (bitboards of attackers to 64 squares)
    BITBOARD AttacksTo[64]
from scratch at each node. I tried to do this incremementally and it quickly got
messy and buggy because of sliding pieces, castle, en passant.
How do you attack attack boards (even the conventional type)?
