Here is a third simpler patch which only implements the Knuth's modulo, 
where the remainder has the same sign as the divisor.

I would prefer this version 3 (one simple modulo based on Knuth 
definition) or if there is a problem version 2 (all 3 modulos). Version 1 
which provides a modulo compatible with C & SQL is really useless to me.
