I guess that makes sense but I wonder if the default alignment should be set to "MIN (size of vector, BIGGEST_ALIGNMENT)" instead so that we don't default to an alignment larger than we know we can support. Or perhaps there should be a way to override the default alignment for vectors on systems that don't require natural alignment. Steve Ellcey [EMAIL PROTECTED]
