Will do. But after looking at a buildbot regression tonight, I'm starting to lean towards the unsigned option again: otherwise we either need our ErrorVector data type to become complex-valued or we're forced to have inconsistent behavior for --enable-complex. --- Roy ------------------------------------------------------------------------------ Everyone hates slow websites.
