More on compiler options, this time with long integers

It's interesting. In both case below (testing the first million natural numbers) the compiler options differ by ---xarch=amd64. The consistent options were ---fast ---xlibmil ---xlibmopt
|Data Model||Wallclock time|
This I find rather strange. Why is it that longs in 64bit mode make execution nearly 6 seconds longer?
