I assume you mean "compare pybench on Python 2.4.3 compiled under" etc.
Unfortunately, I suspect the ex-officio gcc defenders will only react by
finding yet another quibble (anything to avoid admitting that gcc may
not be as good at optimizing as a _Microsoft_ product -- perish the
thought!), therefore I'm disinclined to invest my scarce free time in
that particular endeavour.
