I hold with Stefan's reasoning. We should not change --with-wide-int to become the default. --with-wide-int as a default benefits one group (most users on 32-bit platforms) at the cost of another (users on 32-bit platforms whom it would slow down, and who would need to disable it). Also, it does not affect those who are becoming the predominant audience (users on 64-bit platforms). Thus, I don't see it as a necessary change, especially if "vlf" is a viable alternative. Lastly, 32-bit power users can configure using --with-wide-int. Making this change requires further tests, documentation on how to disable wide-ints (and why), and changes the status quo without demonstrating a compelling benefit. If it had no costs at all, I'd say it was the "right thing to do"; but it's not zero cost, and the benefit does not appear to justify the change. John
