Hans Johnson (hans-johnson@uiowa.edu) discovered a bug in ./configure of iv-15 under RedHat 7.3, which has now been fixed (the solution was to simply touch the configure file, which was being remade unnecessarily, and the files that make it are not up-to-date on 7.3). This fix was from Michael Hines, who is supporting iv-15. The new tar file is on both the pdp++ and hines ftp servers. - Randy
