So this is a 64bit division problem somewhere along the lines that needs
to be using one of the normal helper functions.

What are they?

Sounds like you need to go back and take some care about how we do this
in SPL.  Given the current gcc issue wrt merging strings together, we
may need to be more careful about what files we compile and link for SPL
in this case and perhaps need to split a file or two up.

Per commit is good for development but I really prefer to see the final
totals, can you please report that too?  Thanks.
