commit aa630a928a586fd8dc8a087337c3462d7f4fd1c6
Author: Stefano Lattarini <address@hidden>
Date:   Sun Jun 24 17:57:10 2012 +0200

    tests: avoid several spurious failures on Solaris
    
    * t/ax/is_newest: Rewrite to be Bourne-compatible, for /bin/sh shells like
    Solaris' that are not POSIX-conforming.  The script is so small that such
    a rewrite is easier than going through the hoops that would be required to
    ensure this script is always executed with a POSIX shell.
    * t/ax/is: Add a comment stating that this script is to be kept Bourne
    compatible as well.
