Becomes much faster after msvc compiler changes, or because of what?

Source code for this benchmark would be interesting, and pre-built binaries
too. What should be compared is the difference between wine and windows under
same conditions, so statically linked binary on wine vs statically linked
binary on windows, and so on. That's assuming benchmarks are measuring what
there are supposed to.
