this is quite a useless thread, do you honestly think anyone here will run an application on a P4 that will be affected by a bug? No, they are probably so insanely small, you wont even notice that 8.90374627632E-14 * 7.23475684736E-765 Is off by one one billionth of a percent of a tenth of whatever.
If it runs windows, its good enough for you.
