I have bootstrapped and tested this patch (with FLOOR renamed to 
FLOOR_DIV, and the definition changed to simply be x / y) on 
i686-pc-linux-gnu, ppc64-linux, and powerpc-darwin.

I'll be checking it in in a few hours, to give people time to object.
The interchange tests are working and will be submitted sometime today, 
hopefully.
