Ah yes, I can understand that, especially that you are often working on very large sets of packages like texlive or qt4. > Anyhow, the point is not this, the point is that we have stuff which > doesn't run on the lowest denominator that we support and that can be > quite surprising, even for me.

Maybe we can have some more thoughts on the base cpu level for x86 from other maintainers?
