Very good point, and even if we went down that road one could argue we
should only go for IP32 with long's being 64 bit.

I see the drawback... :-D But maybe Linux provides enough open-source alternatives to existing ISV libraries to limit the number of ISV's impacted by this kind of forced limitation...?

BTW, do you know what is the choice on Linux/ppc64 vs. the previous Linux/ppc implementation on the same topic(data-model sizes)?

Just say no ;)
